The Professional Best Automotive Test Light

You may ask ‘why’ choose one automotive test light over another? The answer is simple. Each automotive test light comes with its own set of features and benefits. Each of those features and benefits will allow you to purchase the one that suits your needs best. Allowing you to quickly diagnose the electrical problems you find.


If you are not familiar with these features, then you might end up buying a product that doesn’t meet your expectations. So, rather than rushing out and buying the first one on the shelf. Check out the features and benefits each product offers you so you can purchase the perfect test light for you. 


Features and Benefits of Automotive Test Lights

There are many different features and benefits that you look for when purchasing an automotive circuit tester. We have compiled a list of what we believe are the most important below.


Bulbs

LED technology has become very popular in today’s world. Test lights have followed this trend. While most new test lights come equipped with LED bulbs. Some test lights are still equipped with incandescent bulbs. 


Incandescent bulbs can still offer benefits over LED bulbs. The current draw of an incandescent bulb for example is higher. This causes a higher load on the circuit which can make it effective when testing for circuit issues. 


Voltage Range

The range of voltages of a test light indicates how much voltage the test light can handle. Best automotive test lights that you will find will be rated for between 5-30 Volts. There are some systems that operate with higher voltages than this but we would recommend using a multimeter in this situation.


Our suggestion is to purchase a test light that is capable of testing 20 volts or above. This will ensure that you can test charging systems without fear of damaging your test equipment. 


Depending on the voltage range that you are testing, the brightness of the light will vary. This is important to note while you are diagnosing with your circuit tester. 


Cable Length

Depending on where you are completing your testing, cable length can be important. If the cable is too short you may have to use a separate jumper wire to properly test the circuit. 


We suggest looking for the longest cable possible when purchasing a test light. However, if you do require a longer cable, invest in a good quality jumper wire kit. 


Insulated Probe

When trying to probe wires in hard to access areas this can be important. The probe is the portion of the circuit tester that is used to “contact” the wire that you test. If the probe is insulated this will prevent you from accidentally shorting out against something you should not have touched. 


Easy to Read Display

For those of you looking to purchase an LED test light, a few other unique things are important. An LED screen with large numbers, as well as the ability to change color from green to red depending on the polarity. These features can help during the diagnostic process.
