Buying Guide: What To Consider When Select Automotive Test Light

automotive test light

a) Bulb Test Light vs. LCD Test Light

Typically, the bulb-based variant is the cheapest option. An incandescent bulb is used as the indication light. The bulb test light’s plus point is that the bulb can be replaced. There is an option to change the bulb if it has been blown out or is dead. This light bulb may survive for a long time if the body quality is good.

The one with LED light indication, LCD display, voltage reading, and computer safe rating, on the other hand, may be able to charge a little more. The one with the bulb is more expensive, but it’s still a good deal. Buying more than that is not advised.

b) Size Clip

The clip (ground) size and kind should be taken into account as the most important consideration. Slippery, open or large, and oversize are all things to look out for while purchasing.

c) Computer Safe

Using a bulb test light is a disadvantage since they are not safe for use with computers. The incandescent bulb consumes power and may put some circuits in jeopardy. In certain cases, some test lights are regarded computer safe because they drain so little power that they pose no risk to the vehicle’s computer and other control components.

This sort of test light is often powered by a battery or an external source, such as a cigarette lighter. You can get one that appears like a bulb, but is actually LED-powered. It is possible to lower the current draw and lessen the risk to the car computer by using LEDs as indicators.

d) LED Indicator

There are three types of light indicators: LED type (using one LED and one transistor) and 3). Incandescent bulb type. Type of polarity, either positive or negative (uses red and green LED with a circuit board).

If you are concerned about the safety of your vehicle’s electrical system, you should avoid using a bulb. Choosing a model with a very low current draw is also the safest choice. The LED indicator lets you know if the current is there or missing by just looking at it.

e) Cable Length

This characteristic must be quantifiable. Longer cords are better than shorter ones since they may cover a wider area. Long cables, on the other hand, might be difficult to store since they take up a lot of room. As a result, we recommend purchasing the coiled version to simplify the process of keeping it tidy.

f) Operating Voltage Range

It’s critical that you understand the cars’ voltage systems before you begin testing. Allows you to pick an ideal test light for it. The old-style 6-12 volt test light will not be accurate if you have a hybrid automobile with a 24 voltage system.

When it comes to pre-1950 autos, a 6-12 volt test light is the best option. Our recommendation is straightforward: if at all feasible, go with a model that can run across a larger variety of voltages.

g) Relief Spring

As a result, it prevents the cord from bending for an extended period of time, which can lead to the cord breaking. This seemingly insignificant element is actually critical in ensuring the cord’s long-term viability.

How to Use A Test Light

It’s really simple to use a test light. However, you must first ensure that this utility functions as planned. The alligator clamp may be attached to the battery’s negative terminal, and the probe can be pierced through the positive terminal to complete the circuit. You can tell whether the light is operating properly if the battery is plugged in and the light is bright enough to see.

Fuse testing is the most prevalent usage of a test light in automobiles. Using a test light to check fuses is a breeze. Disconnect the power cord and check the fuse box for damage. After that, secure the foundation with a clamp.

It is possible to connect the test light’s clamp to the battery’s negative terminal in this scenario. Start with one end of the fuse and work your way out. There is power if the light or other indication comes on. Because if you don’t, it’s going to blow.

Conclusion

It’s not out of the question that it may cause a headache because there are so many models to choose from. If you take the time to pick your favorite, you may end up with the best option. We can’t choose a single solution because everyone’s needs are unique.

The Jastind JTCVT-01B is the only most suitable test light for everyone since it supports a broad variety of voltage systems and a long coiled cable that can reach down to the farthest object to be tested.

It’s safest to use if you can find the one that consumes the least amount of power. The cordless test light would be your second choice because it is easy and safe.
