Let's have a look at the most significant points below!

Types Of Timing Lights

Two main types and two main designs of timing lights are available.

This light can be used for checking the timing when the vehicle is idle.

This model allows for the timing to be adjusted to different engine outputs. This extra flexibility is often sought by mechanics who work on race or performance engines.

It is either a pistol grip or a pencil grip.

Pencil grips: These are more portable, easier to use in confined areas but can be difficult to hold. They also have only basic features. It is usually battery-powered, so compatibility with 12-volt and 6-volt systems are not an issue.

Pistol grips: These models are becoming more common and provide extra details such as battery and alternator voltages, dwell time (the amount of time that the charge is kept in the distributor coil), and the tachometer for engine revolutions per minutes.


It is not necessary to wear any protective gear when setting your timing, but working on engines can be dangerous, especially if distracted. To avoid any accidents, you should always be alert. It's always nice when your child offers to help, but make sure that they are old enough to understand what is going on. Tell them which areas are safe for them to assist and which ones are not. Keep them out of your garage until the job is done if they're not old enough.


When using a basic timing light, you can adjust the scale for fire and timing by adjusting idle RPMs. In some cases, however, issues with vehicles can occur at high RPMs. To fix these anomalies, timing lights should also be accurate at high RPMs.

The majority of timing lights work well up to 10,000 RPM. If you deal with superbikes often, you may want to consider a more accurate option, such as one that can go up to 14,000 RPM.

What Timing Lights Do

In conjunction with these marks, a timing light is used. A cable is attached to the number one spark plug, which detects an electrical pulse sent by the plug when it fires. This electronic signal is then sent to the timing light, causing it flash.

The timing marks will appear at zero if the timing is correct. The timing light flashes when the piston is at the optimal position. This creates ideal combustion.

You'll notice stationary marks a few degrees either before or after zero if it's fast or slow. The timing light does not make the adjustments; it simply shows whether or not the timing is right. Most of the time, zero is correct, but race engineers may advance or retard the ignition to alter performance at different rev ranges.

Build Quality

Checking the quality of the construction is a crucial part of the process. You must first check the cords' quality, as a timing lamp involves so many electrical connections. Then, check the quality of the entire timing light. The outer housing should be made of ABS so that it can easily withstand drops and shocks.


It depends on whether you're buying it for personal or professional use. You may already be familiar with the specifications of your vehicle if you are buying one for personal use. For example, its battery capacity, ignition system, or 2-stroke or 4-stroke engines, etc. If you can find a light that matches the configuration of your car, you're in luck.

If you are buying it for professional use, perhaps you own the most reputable auto repair shop in the area. You need to have the best tools on hand. If you are in this situation, a timing lamp that is compatible with all types of ignition systems and engine types will be the best choice for you.

Assessing The Job

You need to determine if the task can be completed. The majority of motors manufactured since the 1980s use electronic ignition or breakers. Most motors made since the 1990s do not have spark plug or distributor cables. The hood is a lump of plastic with no features. You should have the words "Hands Off!" on it. Unless you own a computer you won't be able to change the timing of that car.

You will see a series of timing marks on your motor. They are usually at the end of the pulley on the crankshaft. Sometimes, they are on the flywheel or fan pulley. Other times, they can be on the cover of the timing belt/chain. These marks are required to use a timing lamp.

It's important to note that some high-end ignition timing lights claim they are compatible with electronic, computer controlled, and distributorless systems (DIS), which is a bit misleading. The instrument is not defective - it can provide all the information you need - but you cannot adjust the timing without a computer system, which you'll only find in professional shops and dealerships. You can tell if there's a problem, but you can't fix it.

Ignition Timing 101

The ignition timing in a gasoline engine sends an electrical current to each sparkplug at predetermined intervals. Diesel engines do not have sparkplugs. In older vehicles, the spark plug cables are spread out all over the distributor. According to one expert, the V8 engine distributor looks like a rubber Octopus!

Your timing can run out due to wear and tear. The timing chain will eventually stretch out. Collectors' and classic vehicles may have distributor points that will need to be changed sooner or later. It could be that your older vehicle's engine is shaking a lot! It doesn't matter what the cause is, it just won't run as well as it should.

Lead Length

Be sure to check the cords too. The standard cable length of 4 feet is sufficient for most vehicles. It is always a good idea to have a few extra feet of cord. A longer cable is more useful if you are practicing on different vehicles, such as cars and trucks.

Final Thoughts

To conclude, the following are the top quality brands that created the 12a timing light: Es, Actron, Allsor. Since new discoveries are made, 12a timing light will be informed. We look forward to often welcoming our pages to remain up to speed on the latest updates.


1. Can I Set A Vehicle’s Timing Without A Timing Light?

Some older engines are capable of this, but not all. If you are not an experienced auto mechanic, then you will need to use a vacuum gauge. The procedure is more complicated and less accurate. A timing light is a relatively inexpensive investment that's worth it if you plan to perform this task on a regular schedule.

2. Do Timing Lights Need Batteries Or A Mains Connection?

Some use internal batteries (usually pen type) and others use the vehicle's battery. Others use the battery in the vehicle. These are distinguished by the red and black wires that terminate in crocodile clips. Your vehicle's battery will provide all the power that you need as long as it is in good condition. Use the tips in this article to properly attach your timing lamp.

3. Can Timing Lights Be Used On Motorcycle Or Marine Engines?

A timing light should work on any gasoline-powered engine, provided you can read the marks and shine the light at them. You'll need to double-check the actual procedures. There is a lot of information available online. However, you might need to be patient in order to find all the details.
