When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works

A properly timed engine in a car or truck delivers its full potential. When not, performance is sluggish and inefficient. We analyzed the market to determine which timing lights for automobiles and trucks perform the best.

We’re well aware of the value of such a device for revitalizing worn-out motorbikes, automobile engines, and even lawnmowers.  Having a timing light readily available in the garage is necessary if you care about the condition of your machines.

Thus, we have compiled the best offers as well as the informative buying guide on timing lights, which you should investigate and seize at this very now.

A Timing Light: How Does It Work?

The spark plug wire fire pulse can be “read” by the inductive clamp. The timing gun detects the electric charges and releases a light pulse simultaneously as the coil pack or distributor fires thru the wire to the spark plug.

The timing marks on the engine’s harmonic balancer or the crankshaft pulley are a helpful reference point. This is where a timing gun comes, as you can use it to compare the markings here with those on the timing belt cover.

When you press the button when the engine is on and the timing light is plugged in, the light will flash to draw attention to the current timing. This is clearly displayed as a degree scale.

A Timing Light May Help You Solve These Problems

If your modern engine has a distributor, a timing light can be just as helpful as it is on older carbureted vehicles. If an engine won’t turn over and you can’t figure out why you can use a timing light to determine whether or not the spark plug wire is receiving a pulse when you turn the crank. If it fails to pick up the electronic signal, you know the problem is likely related to the ignition system.

Though it can detect sparks, the timing light is so named because of its principal function of determining whether or not the ignition has been properly timed. These are some problems where a timing light becomes helpful:

1. Knocking Sounds in The Engine

The pinging or knocking noise an engine makes typically occurs when the fuel-air mixture in the piston ignites prematurely in pre-ignition or detonation. It sounds like someone is pounding the inside of the engine, typically when you’re speeding or under stress. 

Using fuel with a lower octane rating than what the engine needs or having too many residues inside the fuel system could also contribute to this problem. 

Using a fuel system cleaning and gas with a higher octane rating can help with knocking and adjusting the timing. When pre-ignition is detected, the antiknock sensor in modern engines reports this information to the engine control computer, which then modifies the timing.

2. Absence of Spark Advance

If your engine accelerates poorly yet idles smoothly, the timing is probably not being advanced. Distributor timing in a classic car was controlled by mechanical or vacuum advances that changed with engine speed. Because the cylinder is moving more quicker, the spark can ignite it sooner.

Engines often have a timing system that advances as the engine rpm increases to maintain correct combustion. The signs are the same, even though the distributors in modern cars manufactured between the mid-1980s and the late-1990s are computer-controlled.

To ensure proper spark advance, have the engine revived while you run the timing light. The timing mark should shift as the RPMs increase. That’s why it’s best to have your buddy adjust the throttle in the meantime.  

3. Check Engine Light Problems

When something goes wrong with a modern car, the check engine light comes on. If a cylinder misfires, the PCM will record an error code. While the error code won’t reveal the root cause of the problem, it should help pinpoint which cylinder is malfunctioning. After that, connect the induction clamp and turn on the timing light.

Types of Timing Lights

There are at least three types of timing lights currently available on the market. They work similarly to each other except that they may have different power sources or support the MSD.

1. Inductive Timing Lights

These devices, known as inductive timing lights, use a fixed Xenon bulb to precisely time both two- and four-cycle motors. Many of these lights also have buttons or knobs to advance the light to reflect the timing at different RPMs, which is really helpful.

More advanced timing light products come with a tachometer for keeping tabs on engine speed and a dwell meter for keeping track of how long the coil is being charged.

2. Advanced or Adjustable Timing Light

A microprocessor in an adjustable or advance timing light delays the strobe by a user-selected amount. That brings the balancer’s “TDC” mark back into line with the book’s marks. At high engine speeds, when the distributor is constantly shifting, a regular inductive timing light just cannot keep up.

Some brands of adjustable timing lights on the market vary in how precisely they function. This means you must thoroughly inspect any merchandise prior to purchase. Read the reviews left by previous customers to get an idea of the reliability of the service.

3. Cordless Timing Light

You can get a timing light product that runs on batteries if your battery and cables aren’t under the hood like in exotic vehicles or race cars. Therefore, the battery from which the light draws electricity is not required to be within close proximity in order to properly time the engine. In addition to being cordless, a battery-operated timing light frees you from having to deal with an extra cable.

4. Digital Timing Light

Microprocessor-controlled circuitry and an LCD or LED display make it simple to read RPMs and select a degree on digital timing lights. The current selection on most digital timing lights is able to range from 2 to 4 cycles, and the RPM display can go as high as 9,999. There is typically a switch that can be toggled for that function.

5. MSD-Supported Timing Light

It is important to have a timing light that is compatible with your vehicle’s multiple spark distribution system (MSD) if you own one. If multiple spars are detected by a normal timing light, the engine cannot be timed. Ensure the timing light product that is compatible with the MSD in your vehicle.

What to look at before buying a Timing Light

Even if you’re more familiar with the applications of timing light than we are, choosing the best product might still be a daunting challenge.  We’ve put up this buying guide to assist you in finding the best timing light for your needs. 

Support and Compatibility

Whether you need one for business or play makes a difference in the type you should choose. If you use it only for yourself, you probably already know all about your vehicle’s technical specifications, such as its ignition systems, battery voltage, type of engines, and so forth.  You’ll be in the clear if you can obtain a timing light product that works with the make and model of your car.


Adjustments of firing and timing scale are typically made at idle RPMs, a problem that can be remedied by any inexpensive timing light. However, high RPMs are sometimes the first to reveal automotive problems. Therefore, the timing light needs to be precise even at high RPMs in order to correct such irregularities.

You can rely on most timing lights up to 10,000 RPM with no problems. If you frequently work with high-performance vehicles, though, you may want to upgrade to a more precise model that can handle speeds of up to 14,000 RPM, for example.

Cable Length

You shouldn’t only focus on the timing light itself, but also make sure that everything is in working order, including the cords. Although the typical cable length of six inches is plenty for most cars. Having a few feet of extra cord length is a nice bonus. You may need longer cables/leads if you plan on practicing on a variety of vehicles, from cars to larger vehicles like trucks. 

Robust Construction

Another important step is the final inspection of the product’s construction. As with any device that relies on electricity, the quality of the cables used in conjunction with a timed light is of paramount importance.

After that, you can examine the timing light’s overall construction to ensure accuracy. The timing light’s exterior casing should be made of sturdy ABS plastic to ensure it survives accidental drops from great heights.


How do you set timing without a timing light?

Hold the brake and revive the engine when the engine is warm to adjust the ignition timing by ear. Move it forward until you hear a ping, and then pull it back until the rattle stops.

What is an inductive timing light?

The inductive timing light features an on/off touch switch for simple, universal timing. Tool that is straightforward and can be used by anybody to set and check initial timing, centrifugal advance, and vacuum advance in gas cars. 

Do I need a timing light?

If your vehicle is equipped with a distributor, a timing light will reveal the problem. Typically, a car’s engine would not function without spark plugs to ignite the fuel and produce the necessary energy to move the vehicle.

Will a 12-volt timing light work on a 6-volt system?

As the neon timing light is wired right to the spark plug, it may be used in any vehicle as long as the spark plug is wired to provide power. It is possible to use a 6-volt system with most 12-volt timing lights.

Can you use a timing light on newer cars?

If your modern engine has a distributor, a timing light can be just as helpful as it is on older carbureted vehicles. If an engine won’t turn over and you can’t figure out why you can use a timing light to determine whether or not the spark plug wire is receiving a pulse when you turn the crank.

Final Words

We trust that you have carefully considered each timing light possibility shown above. With the reviews, key features, advantages, and negatives we’ve outlined here, choosing a decision should be a breeze.

If this is your first time purchasing such a gadget, we strongly advise reading the buying instructions thoroughly. Though it’s unlikely that you’ll need our aid if you’re having trouble settling on a timing light for your toolkit, here are a few suggestions from our own experience that we think would be useful.
