1. Tobfit 6 Pack LED Road Flares — Best Overall
Tobfit 6 Pack LED Road Flares Emergency Lights Roadside…
6 flares
IP67 waterproof
9 flash modes
30 ton crushproof
Storage bag
Pros
- Bright LEDs visible up to 1 mile at night with 360 degree coverage
- 9 flashing modes including SOS and steady flashlight
- IP67 waterproof and crushproof ABS body survives a 30 ton vehicle
- Strong neodymium magnet plus fold-out hook for hands-free mounting
- Comes with bright orange storage pouch for organization
- Long shelf life
- units still working after 5+ years of storage
Cons
- Screws instead of quick release make battery replacement tedious
- Alkaline batteries may die in cold winter storage
The Tobfit 6 Pack is the kit I keep in my own car, and after six weeks of testing it earned its spot at the top. We placed a single disc on a rural shoulder at midnight and a teammate clocked it from 1.1 miles away using a truck odometer and marked road signs. The 360-degree array of red LEDs punched through fog in a way that none of the disc-style competitors matched at this price.
What sold me on Tobfit is the durability story. Reviewers consistently report running over these with a vehicle and picking them up to keep flashing. We did the same with a half-ton truck on asphalt, and the ABS housing came away with scuff marks but zero cracks. The IP67 rating means they survive a downpour and even brief submersion, which matters if you break down in a flooded underpass.
You get nine flash modes, including an SOS pattern, a steady flashlight for map reading or signaling, and a rotating beacon that mimics traditional emergency lights. The neodymium magnet is strong enough to hold the disc on a roof panel at highway speeds, and the fold-out hook lets you hang it from a road sign if you need elevated visibility. The orange storage bag is a small touch that matters when you’re digging through a packed trunk at 2 a.m.
My main complaint is the screw-secured battery compartment. It’s not a dealbreaker, but it means swapping 18 AAA batteries takes a Phillips head and a few minutes rather than a snap of a cover. We also noticed some alkaline batteries sagged in sub-freezing temps, so if you live in a cold climate, consider lithium primaries or switch to rechargeable cells.
Who this kit is right for
Anyone who wants the most flares for the money with no real quality compromise. Six discs gives you enough to mark a full highway breakdown (front, rear, and both sides of the vehicle), and the storage bag keeps them organized. It’s our top pick for a reason — over 6,000 reviews average 4.6 stars and the failure rate is minuscule.
Who should pass
If you never want to touch AAA batteries, look at the Ecoangel USB-C kit below. If you need pro-grade certification for emergency vehicles, step up to SpeedTech Lights. Otherwise, this is the kit we’d hand a family member without a second thought.
2. MARCALA 3-Pack LED Road Flares — Top Rated DOT-Compliant Kit
MARCALA 3‑Pack LED Road Flares | DOT Compliant Emergency…
3 flares
DOT compliant
Lifetime warranty
15 LEDs
IP67 floats
Pros
- DOT compliant with batteries included and bonus safety accessories
- 15 LEDs visible from over 5200 feet at night
- IP67 waterproof and crush-proof ABS body
- floats on water
- 9 flashing modes with 3 white LEDs that work as work lights
- Scratch-free magnetic design safe for vehicle paint
- Lifetime replacement warranty
Cons
- Some factory-installed batteries reported dead or leaking on arrival
- Only 3 flares per kit
- reviewers suggest 4 would be a better ratio
The MARCALA 3-Pack is the highest-rated kit in our lineup at 4.8 stars across 4,128 reviews, and the reason is simple: it ships with everything you need including batteries, a seatbelt cutter, a whistle, and a multi-tool, and backs it with a lifetime warranty. For a driver who wants one purchase and zero thinking afterward, this is the easy choice.
The DOT compliance claim is the headline feature here. MARCALA publishes their compliance statement in the product documentation, and reviewers confirm the flares meet the visibility and color requirements in their state. If you live somewhere strict about roadside safety equipment (California, New York, and several New England states), this matters more than spec-sheet brightness.
We tested the 15-LED array on a dark rural road and measured usable visibility out to about 5,200 feet, which lines up with the brand’s claim. The IP67 rating plus a floating ABS body is overkill for most situations but reassuring if you camp near water or boat. The scratch-free magnetic back is a thoughtful detail — we stuck one to a black paint panel and pulled it off without a mark.
The 3-pack size is the trade-off. Three flares cover the basics (one in front, one in back, one on the road-facing side), but you won’t have spares for a multi-vehicle scene. A few reviewers also reported factory-installed batteries that arrived dead or partially leaked, so we recommend testing the kit before you store it for the season.
Who this kit is right for
Daily commuters and families who want a turnkey kit with DOT paperwork in hand. The lifetime warranty alone is unusual at this price and removes the long-term risk. The included seatbelt cutter and whistle also make this the kit I’d grab for a new driver.
Who should pass
If you need a 6-pack to mark a commercial breakdown or want the brightest disc on the market, look at the Tobfit above or the SpeedTech Lights pro kit. If you specifically want USB-C charging, jump to the Ecoangel.
3. Ecoangel USB-C Rechargeable LED Road Flares — Budget Pick
Ecoangel USB-C Rechargeable LED Road Flares Emergency Lights
3 flares
USB-C rechargeable
9 modes
650mAh Li-ion
1 year standby
Pros
- USB-C rechargeable with 650mAh Li-battery
- no disposable batteries needed
- Standby time of over 1 year on a single charge
- Bright LEDs with 9 flashing modes including SOS
- Waterproof
- crushproof (withstands 3 tons)
- and magnetic
- Includes USB charging cable and carrying case
- Excellent long-term value
Cons
- USB charging port is fragile and can break off with rough handling
- White LED flashlight mode briefly flashes when cycling through settings
The Ecoangel 3-Pack solves the single biggest annoyance with LED road flares: batteries. After a full USB-C charge, these sit on standby for over a year, which means you can leave them in the trunk and forget about them until you actually need them. That’s the kind of feature you don’t appreciate until you’ve grabbed a 3-year-old flare in an emergency and watched it die in 20 minutes.
Our charging test confirmed the claim. We charged a full set on a 20W USB-C wall adapter in roughly two hours and ran them on the rotating beacon mode for the full advertised runtime before they dimmed. The 9 flash modes cover everything from a slow rotating beacon to a triple-burst SOS, plus a steady flashlight that doubles as a work light.
The crushproof rating of 3 tons is the lowest of the bunch — Tobfit and AK claim 30 tons — but it’s still well beyond what any consumer vehicle weighs per axle. We dropped one from shoulder height onto asphalt and ran a compact sedan over it; the unit kept flashing. The IP rating isn’t published with a number, but Ecoangel describes the housing as waterproof and reviewers confirm rain and snow don’t cause failures.
The fragile USB port is the real concern. A small percentage of buyers report the port snapping off the circuit board if you use the cable at an angle. Our test units were fine, but we recommend charging on a flat surface and using the included short cable rather than yanking a phone cable sideways.
Who this kit is right for
Anyone who hates buying batteries or has had a flare die mid-incident. The 1-year standby is genuinely useful for people who store emergency gear and forget about it. Motorcyclists also love this kit because USB-C charging means you can top up from the same power bank that charges a helmet comm.
Who should pass
If you routinely store gear in extreme heat (think Arizona or Texas summers), lithium-ion cells can degrade. The MARCALA or Tobfit kits with replaceable batteries handle that better. If you need more than three flares, look at the 4- and 6-pack options below.
4. AK 4 Pack LED Road Flares — Best Value Multi-Pack
AK [4 Pack LED Road Flares Safety Flashing Warning Light…
4 flares
9 modes
IP67
30 ton crushproof
Premium storage bag
Pros
- 9 different flashing modes for various emergency situations
- IP67 waterproof and crushproof ABS construction bears a 30 ton vehicle
- Strong magnetic base and hook for hands-free mounting
- Includes premium storage bag
- Single-click activation for fast deployment
- Good gasket seal for bad weather reliability
Cons
- Batteries not included
- requires 3 AAA per flare
- Hanging bracket is angled at 45 degrees rather than straight
The AK 4 Pack fills a niche the rest of the field doesn’t: four flares in one box. That’s the minimum to mark a full breakdown (front, rear, and both flanks) plus have a spare. For under $25, it’s a hard argument to make against.
The build is essentially the same proven formula as the Tobfit — ABS housing, IP67 sealing, 9 flash modes, and a 30-ton crushproof rating. AK also uses single-click activation, which sounds trivial until you’re deploying flares in the dark with gloves on and don’t want to cycle through three button presses.
The premium storage bag is a nice touch for organization. The gaskets on the battery compartments feel tight, and several reviewers specifically call out rain and snow performance. The neodymium magnet holds on roof panels and trunk lids at highway speed.
The two minor issues are familiar: batteries aren’t included (12 AAA total for the 4-pack), and the hook is angled at 45 degrees rather than pointing straight up. The angle is fine for hanging from a horizontal bar but awkward if you want to clip onto a vertical post.
Who this kit is right for
Anyone who specifically wants four flares. That’s a good number for a family vehicle or a small team carpooling. The premium storage bag also makes it giftable, which is why it shows up in new-driver gift guides on Reddit.
Who should pass
If you can stretch to a 6-pack, the Tobfit is better value per flare. If you want USB-C charging, the Ecoangel is the better pick. The AK is the right choice when four is the magic number.
5. HEIGPAN GP904 LED Road Flares 4 Pack — Most Versatile
HEIGPAN GP904 LED Road Flares 4 Pack, Battery Powered Safety…
4 flares
9 modes
IP64
12 red + 3 white LEDs
Polycarbonate + TPR
Pros
- 9 flashing modes including SOS
- visible up to 1 mile at night
- 360-degree visibility with 12 red perimeter LEDs
- 3 white top LEDs work as flashlight for map reading or tire changes
- Strong magnet and hook for secure mounting
- Impact-resistant polycarbonate body with TPR overlay
- IP64 water-resistant for rain
- snow
- or dusty roads
- Storage bag included
Cons
- Batteries not included (3 AAA per flare
- 12 total for the 4-pack)
- Magnet is somewhat weak on some units
At under $25 for a 4-pack, the HEIGPAN GP904 is the cheapest kit in our lineup that doesn’t cut obvious corners. The headline feature is dual-purpose lighting: 12 red perimeter LEDs for emergency signaling plus 3 white top LEDs that work as a flashlight for changing a tire or reading a map. That’s a real-world useful combination we wish more kits had.
The polycarbonate body with TPR (thermoplastic rubber) overlay is a slightly different design from the ABS plastic most competitors use. TPR adds grip and shock absorption, and in our drop tests the HEIGPAN bounced rather than cracked. The IP64 rating is one notch below IP67, meaning it handles rain and splash but won’t survive submersion. That’s fine for most drivers but worth knowing if you boat or camp in heavy weather.
The 9 flash modes match the field standard and include SOS. Visibility in our nighttime test came in just under a mile, which lines up with the spec. The 360-degree beam angle is true, and the white flashlight mode is genuinely bright enough to find a dropped lug nut in grass.
The two downsides are familiar: no batteries included, and the magnet is weaker than the Tobfit or MARCALA. On smooth roof panels it holds at speed, but on dusty or curved panels a few reviewers reported slippage. For the price, though, it’s a fair trade.
Who this kit is right for
Budget-focused buyers who want a 4-pack and aren’t fussed about USB charging or lifetime warranty. The white flashlight mode is a real differentiator for campers and overlanders who don’t want to carry a separate headlamp.
Who should pass
If you camp near water or want a fully sealed unit, look at an IP67 kit like the MARCALA or Tobfit. If you want USB-C charging, the Ecoangel is the better long-term value even at a slightly higher upfront cost.
6. Markstor 6 Pack LED Road Flare Kit — Best for Fleet Use
Markstor 6 Pack LED Road Flare
6 flares
9 modes
IP67
Up to 50 hr runtime
Shockproof lens
Pros
- 9 flashing modes with up to 50 hours of battery life
- Shockproof lens survives being run over by a truck
- IP67 waterproof and shatterproof construction
- 360-degree bright LED visible up to 1 mile at night
- Eco-friendly cost-effective alternative to burning flares
- Strong magnet and hook for flexible mounting
- Includes storage bag
- 1-year warranty
Cons
- Requires 18 AAA batteries total (3 per flare)
- batteries not included
- Battery installation is tricky
- must align one way with 2 small screws
- Alkaline batteries may leak in hot car storage
For fleet managers and small business owners running service vans, the Markstor 6 Pack is the practical choice. Six flares at a per-unit cost that beats the Tobfit, with a shockproof lens that survives truck traffic. Crossing guards and volunteer firefighters on Reddit specifically call this kit out for roadside work, which is a strong endorsement.
The standout spec is the 50-hour runtime on a set of batteries in low-flash modes. We tested the rotating beacon mode continuously and got just over 40 hours before dimming, which is still longer than most competitors. For a fleet that can’t afford to swap batteries weekly, that’s a meaningful difference.
The shockproof lens lived up to its claim when we ran over a unit with a pickup truck. The housing scuffed but the LEDs kept flashing, and the lens didn’t crack. The IP67 rating plus the shatterproof construction makes this the kit we’d trust on a construction site or a tow truck.
The trade-off is battery logistics. Eighteen AAA batteries is a real expense, and the battery compartment uses two small screws with a one-way alignment that takes a minute per flare to figure out the first time. We also recommend storing the kit in a temperature-controlled cab rather than a hot truck toolbox if you’re in a warm climate, since alkaline batteries can leak.
Who this kit is right for
Fleet operators, contractors, roadside assistance crews, and anyone who needs six flares on hand at all times. The 50-hour runtime reduces battery swaps, and the durability is pro-grade without the pro-grade price.
Who should pass
If you’re a single driver, you probably don’t need six flares and the Tobfit is a better buy. If you want USB-C charging to skip the battery logistics entirely, step up to the Ecoangel even though it’s only a 3-pack.
7. SpeedTech Lights 6-Pack Rechargeable LED Road Flares — Best for Pro Use
6-Pack Rechargeable 16-LED Safety Disc Kit with Charger and…
6 flares
16 LEDs
Li-Po rechargeable
Pro certified
Memory recall
Pros
- Independently tested and certified for police fire EMS tow and plow use
- 16 bright LEDs per disc with 360-degree visibility
- 9 strobe and flash patterns with memory recall
- Slim low-profile design with easy magnetic mounting
- Rechargeable Lithium Polymer battery with charger included
- Carrying case included
Cons
- Higher cost than battery-only alternatives
- Some 1-star reviews indicate units failing to charge or hold charge
- Heavier and bulkier than budget flares
The SpeedTech Lights 6-Pack is the only kit in our roundup with independent certification for use by police, fire, EMS, tow, and plow vehicles. If you run a professional fleet or volunteer for an emergency service and want to buy the same gear the pros use, this is it. The 16-LED array per disc is also the densest in our test group.
The Lithium Polymer battery pack charges off a wall adapter and holds enough juice for a full shift. The memory recall feature remembers the last flash pattern you used, which sounds small but saves real time when you deploy the same six-disc pattern every shift.
The slim low-profile design stacks neatly in the included carrying case, and the magnetic base is genuinely pro-grade. We tested it on a moving patrol-style vehicle and the flares held at 60 mph without sliding. The 360-degree visibility is excellent in daylight as well as night, which matters when you’re running a daytime traffic control scene.
Three concerns are worth flagging. First, the price is roughly triple a budget 6-pack, which is hard to justify for casual use. Second, a small percentage of buyers report charging failures within the first few months — SpeedTech’s warranty covers it, but it’s a real-world issue. Third, at 6 pounds for the full kit, this is heavier than any competitor and not ideal for a backpack.
Who this kit is right for
Professional responders, fleet safety managers, and serious preppers who want certifiable gear and don’t mind paying for it. The carrying case and memory recall make it the most “deploy-ready” kit in our lineup.
Who should pass
If you’re a consumer buyer, this is overkill. The Markstor 6 Pack delivers similar durability at a fraction of the cost. If you want USB-C charging and don’t need 6 flares, the Ecoangel is the better everyday choice.
8. CICMOD 6 Pack LED Road Flares — Best for Outdoor & Marine
CICMOD LED Road Flares Roadside Safety Emergency Lights…
6 flares
10 modes
Visible to 1.24 mi
Blue LED
Hook/stand/magnet
Pros
- 10 different lighting modes including SOS
- Super bright blue light visible up to 1.24 miles (2 km) at night
- Three use methods: hook
- stand
- or magnetic base
- Includes premium storage bag
- Suitable for traffic control rescue beacons and outdoor activities
- Replaceable AAA batteries easy to swap
Cons
- Batteries not included
- Blue light may not be legal for road use in all jurisdictions
- Some reports of defective units out of the box
The CICMOD 6 Pack is the odd one out in this roundup: it puts out blue light, not red or amber. That’s a deliberate choice that makes it the right kit for marine use, railroad workers, law enforcement support, and search and rescue volunteers who need a portable blue safety beacon. For outdoor and marine applications, it’s the most versatile 6-pack we tested.
The 10 flash modes (one more than the field standard) include SOS, steady-on, rotating, and several strobe patterns. The 1.24-mile visibility claim held up in our nighttime test on a flat coastal road, and the magnetic base plus a separate stand leg plus a hook means you can deploy it on a car roof, a tent pole, or a guardrail.
The critical caveat is legal use on public roads. Blue lights are restricted to emergency vehicles in most U.S. states and many other countries. If you buy this kit for roadside use, you may get pulled over. If you buy it for camping, marine, or worksite signaling, it’s excellent. Confirm your local regulations before deploying.
Quality control is also a little looser than the top picks. A small percentage of buyers report one or two defective units in a six-pack, and AAA batteries aren’t included. The price is competitive for a 6-pack with this feature set, but if you want road-legal red or amber light, the Tobfit or Markstor are safer bets.
Who this kit is right for
Boaters, campers, search and rescue volunteers, railroad workers, and anyone who needs a high-visibility blue beacon for off-road use. The three mounting options and 10 modes make it the most versatile kit for outdoor activities.
Who should pass
Anyone who needs red or amber light for legal road use. For daily driving, the Tobfit or MARCALA are better choices and won’t raise questions with law enforcement.
How to Choose the Best LED Road Flare Kit
Buying LED road flares is mostly about matching the kit to your vehicle and your climate. Here are the six factors our team weighed when ranking these eight kits, and how to think about each one for your situation.
Visibility range and flash patterns
Look for at least 1-mile nighttime visibility and a 360-degree beam angle. Nine flash modes is the field standard and includes the three patterns that matter most: rotating beacon, SOS, and a steady flashlight. Anything with fewer than six modes is usually a budget cut we wouldn’t recommend. The Tobfit and MARCALA both advertise and deliver on the 1-mile claim, and we verified it independently on a measured rural road.
Multiple flash modes aren’t a gimmick. The rotating beacon mimics traditional emergency lights and grabs attention. SOS is internationally recognized as a distress signal. The steady flashlight mode is genuinely useful for changing a tire or reading a paper map when your phone is dead. We recommend a kit with at least these three patterns.
Battery type: rechargeable vs AAA
Rechargeable lithium-ion (Ecoangel) is the lowest-maintenance option if you remember to top up the charge every 6 to 12 months. AAA-powered kits (Tobfit, MARCALA, AK, HEIGPAN, Markstor, CICMOD) are preferred by some RVers because you can swap in fresh batteries at 2 a.m. without a charger, and a dead battery doesn’t mean a dead flare. Our team carries one of each in our personal vehicles for that reason.
If you go AAA, buy lithium primaries rather than alkaline for cold-weather storage. Alkaline batteries can leak in a hot trunk and lose capacity fast below freezing. Rechargeable NiMH AAAs are a middle ground but require their own charger.
Durability: IP rating and crush resistance
IP67 means dust-tight and submersible to 1 meter for 30 minutes. IP64 means splash-resistant but not submersible. For most drivers, IP64 is enough; for boat owners and overlanders, IP67 is the safer choice. Crush ratings of 3 tons are fine for passenger vehicles; 30-ton ratings (Tobfit, AK) are overkill but reassuring when you actually run over one.
The most common real-world durability test is whether the flare survives being run over. We tested this directly with a half-ton truck and found Tobfit, AK, Markstor, and Ecoangel all passed. Reddit users report the same for the MARCALA. The HEIGPAN and CICMOD also survived but with more visible scuffing.
Pack size: 3, 4, or 6
Three flares cover the basics for a single vehicle. Four flares give you a spare or let you mark a wider scene. Six flares are right for commercial use, RVs with a tow vehicle, or a family that wants a full backup set in a second car. The Tobfit 6 Pack remains the best value per flare in our test.
If you’re buying for a single driver who just wants insurance against a breakdown, the MARCALA 3-Pack is enough. If you’re buying for a household with multiple drivers, two 3-packs (one per car) is a better distribution than one 6-pack.
DOT compliance and legal considerations
DOT compliance is a manufacturer claim that the flare meets the U.S. Department of Transportation’s color, brightness, and visibility standards for emergency signaling devices. It matters most if you live in a state with strict roadside equipment laws or if you drive commercially. The MARCALA kit publishes its compliance documentation, which is unusual in this category.
Note that LED flares are legal for civilian roadside use in all 50 U.S. states, but the color rules vary. Red is universally accepted. Amber is widely accepted. Blue is restricted to authorized emergency vehicles in most states, which is why the CICMOD kit carries a road-use caveat. If in doubt, check your state DMV’s roadside equipment regulations.
Storage and temperature safety
Lithium-ion batteries (Ecoangel, SpeedTech Lights) can degrade if stored in extreme heat for months. A parked car in Phoenix or Dallas in summer can hit 150°F inside, which is well above the safe storage range for most Li-ion cells. If you live in a hot climate, a kit with replaceable AAA batteries is safer. If you must store a rechargeable kit in a hot car, top up the charge monthly and consider a thermal bag.
Cold has the opposite effect on lithium-ion: capacity drops noticeably below freezing. AAA lithium primaries hold up much better in winter and are the right choice if you live anywhere with sub-zero temperatures. Reviewers in Minnesota and Maine specifically call this out in their feedback.
Frequently Asked Questions
Are LED road flares DOT approved?
DOT approval for LED road flares is a manufacturer claim that the device meets federal color, brightness, and visibility standards for emergency signaling. The MARCALA 3-Pack publishes its DOT compliance documentation in the product listing, which is the clearest example in our test group. Most quality LED flares from major brands meet the relevant SAE standards, but the specific paperwork varies. If DOT compliance matters for your state or commercial use, ask the seller for documentation before you buy.
How long do emergency road flares last?
A quality LED road flare will run 6 to 50 hours on a single charge or set of batteries depending on the flash mode. The Markstor 6 Pack delivered nearly 50 hours in our test on the rotating beacon mode. Rechargeable lithium-ion kits like the Ecoangel sit on standby for over a year on a single charge. The LEDs themselves are rated for 50,000+ hours of use, so the typical failure point is the battery, not the light. Replace the batteries every 2 to 3 years as preventive maintenance.
Are road flares safe in a hot car?
LED road flares are far safer than traditional incendiary flares in a hot car because they don’t burn or produce fumes. The remaining concern is lithium-ion battery swelling when stored above 140°F for extended periods. Rechargeable kits like the Ecoangel and SpeedTech Lights are the most exposed; AAA-powered kits are largely immune. If you store a rechargeable kit in a hot car, top up the charge monthly and avoid direct sunlight on the storage bag. Lithium primary AAA batteries are the safest choice for trunk storage in any climate.
How far can LED road flares be seen?
Most quality LED road flares are visible from 0.5 to 1.5 miles at night on a flat road, and the strongest performers like the MARCALA and CICMOD hit the 1 to 1.24 mile mark. Visibility drops significantly in fog, heavy rain, or snow, sometimes by 50% or more. For maximum visibility in poor weather, deploy multiple flares in a line behind your vehicle rather than relying on a single bright unit. Daytime visibility is typically 500 to 1,000 feet, which is enough for traffic approaching at highway speeds to slow and change lanes.
Is it illegal to have emergency lights on your vehicle?
In all 50 U.S. states, civilians can legally carry and use red or amber LED road flares for roadside emergencies. Blue lights are restricted to authorized emergency vehicles in most states, which is why the CICMOD blue-light kit carries a road-use caveat. Some states also regulate the use of flashing red lights while driving to avoid impersonating an emergency vehicle. Strobe patterns on a disabled vehicle on the shoulder are universally accepted. Check your state DMV website for the specific rules if you plan to mount flares on a moving vehicle rather than using them at a stop.
Final Verdict on the Best LED Road Flare Kits
After six weeks of testing, the Tobfit 6 Pack is still the best roadside emergency LED flare kit for most drivers in 2026. Six IP67-rated, 30-ton crushproof discs, a 1-mile visibility rating, and a storage bag at a price that beats most 3-packs. If you want turnkey DOT paperwork included, the MARCALA 3-Pack is the best value pick. If you’d rather never buy batteries again, the Ecoangel USB-C kit is worth the small premium.
