If your car is shuddering or you experience something called knocking, the ignition system may not be running as smoothly as it should. Rather than take your vehicle to a professional mechanic and end up spending lots of money just to tell you that you have a timing issue, a timing light is a handy tool that you can try yourself first. Cars with older engines are more likely to have timing issues with the ignition system and spark plugs not firing correctly.
Timing lights may require a little technical know-how beforehand when attempting to use one, however, a quick watch of a Youtube video will show you how to use one correctly. Have a browse through our 5 top timing gun lights below to ensure your older engine doesn't fall victim to a bad firing sequence.

Car Engine Timing Light Buying Considerations
What You Would Like to Use It For
If you want a basic timing light where its only purpose is to tell you if your engine’s timing is off or not, making your choice is as simple as reading reviews, manufacturer descriptions, and choosing a light that’s within your budget. But the cheaper options are truly basic, and won’t give you a range of versatility that you would otherwise enjoy if you’re a mechanic or a DIY enthusiast.
The additional features should not be scoffed at. They can help you to learn much more about your vehicle and will allow you to catch and fix minor issues. It will also make fine-tuning your vehicle a breeze, allowing it to operate with much better efficiency for longer periods since it will be fully and properly maintained.
Type of Timing Light
You’ll come across two primary types of timing lights in your search. These are inductive and inline. The most notable difference between the two is the type of connection they feature.
These have a built-in sensor that you will clip around your vehicle’s spark plug. They are a bit more expensive than the inline timing lights but tend to have a better design with more inclusive features.
They will require you to unplug the spark plug from your vehicle first before connecting the timing light. They are cheaper but usually have fewer features and a less-than-favorable design. But they’re great for DIYers that want to avoid electrocution.
Ease of Use and Complexity
A majority of the timing lights that you’ll come across have a pistol shape and a trigger. These are the easiest timing lights to use. Some of them come with a microprocessor that helps to control the timing light, and some may even allow you to easily check your vehicle’s RPM, battery voltage, dwell, and more.
You should also keep in mind what kind of material the timing light is made of, as some are metal. Since metal conducts electricity, it’s best not to buy these types unless you are particularly familiar with safety precautions regarding them.
Additionally, you want to think about what kind of timing light you need: simple or complex. This will affect what you can check in your vehicle, what functions are included, and what price you will ultimately pay for the equipment.
The Final Word
Timing lights aren’t the most essential pieces of equipment for the casual car owner, however, if you’re a professional mechanic or have an older classic car, they are something worth having in the toolbox. Most modern cars probably won't need their engine timed with one of these flashing guns and can have most problems diagnosed with a standard OBD2 diagnostic tool. If you are in the market for one of these guns, then check out the Draper 52616 Xenon as we have chosen it as our best timing light choice overall.
