10 Best Test Light For Cars of 2022


A test light is an important tool to have in your car-maintenance arsenal. It allows you to check for electrical problems quickly and easily and can save you a lot of time (and money) in the long run. But with so many different types and brands on the market, it can be tough to know where to start when shopping for a test light. Here’s a quick guide to help you make the best decision for your needs.

Types of Test Lights

There are two main types of test lights: incandescent and LED. Incandescent test lights are less expensive but not as durable, while LED lights are more expensive but will last longer. If you do a lot of electrical work on your car, it’s worth investing in an LED light; if you only occasionally need to use a test light, an incandescent light will suffice.

Features to Look For

When shopping for a test light, there are a few key features to keep in mind. First, make sure that the light is bright enough for you to see clearly; after all, you’re trying to diagnose an electrical problem, so being able to see what you’re doing is crucial. Second, look for a light with a long cord; this will give you more flexibility when working on your car. Finally, consider getting a light with a built-in clamp; this will allow you to attach the light directly to the battery, making it easier to use.

Pros and Cons of Shopping Online

There are both pros and cons to shopping for a test light online. On the one hand, you’ll have a much wider selection of products to choose from than you would if you shopped in person. On the other hand, it can be tough to tell whether a product is a high quality just by looking at pictures online, so you’ll need to do your research before making a purchase.

Where to Find Reviews

If you’re not sure whether a particular test light is right for you, reading reviews from other customers can be helpful. Try looking for reviews on websites like Amazon or eBay, or searching for customer reviews on Google. Read through several reviews before making your decision—and take them with a grain of salt; remember that everyone has different needs and expectations when it comes to their tools.

How Much Should You Expect To Spend?

Prices for test lights can vary widely depending on the type of light, the features it offers, and the brand. In general, though, you should expect to spend between $20 and $50 on a good-quality test light. If you find a light that’s significantly cheaper than that, be wary—it may not be as durable or effective as more expensive options.

Common Problems You Might Encounter

While using your test light, there are a few common problems you might encounter. First, if the bulb burns out frequently, it’s likely that the quality of the light is poor and you should consider replacing it with a better option. Second, if the cord isn’t long enough or isn’t flexible enough, it will be difficult to use the light effectively—so make sure to get one with a long cord that’s easy to maneuver. Finally, if the clamp isn’t strong enough or doesn’t fit well onto your battery terminal, it will be difficult (if not impossible) to use the light properly—so again, make sure to get one with a good clamp that will stay securely in place.


Test lights are essential tools for anyone who works on their own car—but with so many different types and brands available on the market, it can be tough to know where to start when shopping for one. Use this quick guide as a starting point—it covers everything from what features to look for in a good test light to how much you should expect to spend on one—to help make sure you get exactly what you need before beginning your next car repair project!
