After using the Innova 5568 Pro on my Chevelle and several other project cars, I understand why serious DIY mechanics consistently recommend this timing light. The digital advance feature alone saves tremendous time – instead of rotating the distributor to check total advance, you simply dial it in on the display and read the timing marks directly. This works for advance readings up to 90 degrees, which covers virtually any street or mild performance application.
The built-in tachometer displays RPM alongside the timing reading on a split-screen LED display. I found this incredibly useful because I didn’t need to set up a separate tachometer while checking timing at different engine speeds. The concurrent display of timing delay with RPM lets you verify that your mechanical advance is working properly throughout the RPM range.
Setting up the 5568 Pro takes about two minutes. The inductive pickup clamp slides over your number one spark plug wire, and the power leads connect to your battery. I appreciate that Innova includes color-coded polarity markings on the sensor clips – it eliminates guesswork. The pickup worked reliably on both my 350 small block with plug wires and my friend’s import with smaller gauge ignition wires.
One feature that really stood out during testing was the dwell meter function. If you’re working on older vehicles with points ignition, you can check both timing and dwell angle with the same tool. This eliminates the need for a separate dwell meter in your toolbox. The accuracy proved consistent when I cross-checked against a professional shop’s timing light.
Best For
The Innova 5568 Pro is ideal for serious DIY mechanics, classic car enthusiasts, and anyone who wants professional-grade accuracy without the professional price tag. It’s particularly valuable if you tune performance engines where checking total advance matters as much as base timing.

Buying Guide: How to Choose the Best Timing Lights?
Choosing the right timing light depends on your specific needs, the vehicles you work on, and how often you’ll use it. Here’s what to consider when making your selection.
Understanding Ignition Timing
Ignition timing refers to when the spark plug fires relative to the piston’s position in the cylinder. Optimal timing ensures the air-fuel mixture ignites at precisely the right moment for maximum power and efficiency. If timing is too advanced (spark fires too early), you risk engine knock and potential damage. If timing is too retarded (spark fires too late), you lose power and fuel economy. A timing light lets you verify and adjust this critical parameter.
Digital vs Analog Timing Lights
Digital timing lights feature LCD or LED displays showing timing advance numerically. They’re easier to read and often include additional functions like tachometers and dwell meters. Analog timing lights use mechanical advance dials and require you to interpret timing marks directly. Analog models tend to be less expensive and more durable, while digital options offer convenience and precision.
Power Source Considerations
Most timing lights connect to the vehicle’s 12-volt battery for power. Self-powered models use internal D batteries, which is convenient for motorcycles, boats, and equipment with hard-to-reach batteries. However, batteries add ongoing cost and weight. If you primarily work on cars in a garage, a corded model usually makes more sense.
Key Features to Look For
Advance capability lets you check total timing without rotating the distributor. A built-in tachometer eliminates the need for a separate RPM tool. Bright strobe output matters for daylight visibility. Long cables provide flexibility in engine compartments. Heat-resistant leads improve safety and durability. For more on maintaining outdoor power equipment and small engines, self-powered timing lights often work best.
Compatibility With Modern Ignition Systems
Not all timing lights work with all ignition systems. DIS (distributor-less ignition system) compatibility is essential for many modern vehicles. Multi-spark ignition systems require lights with skip circuitry to function properly. If you work on classic cars with points ignition, dwell meter functionality becomes valuable. Always verify compatibility with your specific vehicles before purchasing.
FAQ
What is the best ignition timing for performance?
The best ignition timing for performance typically ranges from 32 to 38 degrees total advance for most street engines, though optimal timing varies by engine design, compression ratio, and fuel quality. Start with factory specifications and advance timing in 2-degree increments while monitoring for knock. Maximum power usually occurs just before the point where knock begins, but always leave a safety margin to prevent engine damage.
What happens if ignition timing is too advanced?
When ignition timing is too advanced, the spark plug fires before the piston reaches top dead center, causing the air-fuel mixture to ignite too early. This results in engine knock or ping, which can cause serious engine damage including melted pistons, damaged bearings, and cracked cylinder heads. Symptoms include audible knocking under load, reduced power, overheating, and increased fuel consumption. Retarding timing slightly usually resolves these issues.
What are the benefits of retarding ignition timing?
Retarding ignition timing (firing the spark later) reduces the risk of engine knock and detonation, which is beneficial for engines running high boost, poor quality fuel, or in hot climates. It can also reduce NOx emissions and improve engine smoothness at idle. However, too much retard reduces power and fuel economy while increasing exhaust gas temperatures. Turbocharged engines often benefit from slightly retarded timing under boost.
What timing light for MSD ignition?
MSD ignition systems require timing lights compatible with multi-spark systems because MSD boxes fire multiple sparks per combustion event. The Innova 5568 Pro and Innova 3568 both feature skip circuitry that works correctly with MSD ignitions. Self-powered timing lights like the ESI 130 also work well with MSD systems. Budget timing lights without skip circuitry may produce erratic or inaccurate readings with multi-spark ignitions.
Conclusion
After testing these timing lights extensively, the Innova 5568 Pro stands out as the best overall choice for serious DIY mechanics and classic car enthusiasts. Its digital advance capability up to 90 degrees, built-in tachometer, and dwell meter function provide professional features at a reasonable price. For budget-conscious buyers, the OBDMONSTER timing light handles basic timing checks adequately at under $25. Professional mechanics and racing enthusiasts should consider the ESI 130 for its high-RPM accuracy and American-made durability.
When choosing the best timing light guns for ignition tuning, match the tool to your needs. Occasional DIY use on street cars works fine with basic models. Performance tuning and classic car restoration benefit from advance capability. Racing applications demand high-RPM reliability. Whatever your needs, having the right timing light in your toolbox makes maintaining optimal engine performance much easier.
