How to check the operation of car light bulbs?

The safety and visibility of drivers depends in part on the bulbs. It is an indispensable element that keeps you away from various inconveniences. You should therefore check the function of the car bulbs on a regular basis. How do you do this? This article helps you to find out what to check, how to do it and how to pass the bulb test.

Take the light bulb test

There are several standards to follow in today's safety standards. In fact, good lighting will get you far. So, if your car lamp is malfunctioning, test it with a multimeter. For a bulb that looks like it's working well, use a multimeter and tools to remove the headlamp plate and bulb. This is how a multimeter works. A multimeter is used to measure the resistance of a bulb on a voltage-free component or circuit. Once on the Ohm 20k position, place one end of the cord on the side of the bulb, the other touch point is to be placed on the bulb base. Then, if the numbers on the machine's screen move and return to 0, rest assured, the bulb is good. For a burnt-out bulb, even the numbers will refuse to move. You'll need a spare bulb for your car.

Points to check

Today's light bulbs are not good for life. Lights and indicators should be checked. Also, in most cases, it is the car LED that is defective. Otherwise, check the contacts. If the bulb is not clean, clean the oxidation marks on it. You can easily remove it with a piece of sandpaper. Before spraying on the contact spray, wipe off any deposits with a clean cloth. Then, to avoid overheating, check the fuse. Remove the fuse box from its housing and replace it if necessary. With a new fuse, even the faulty bulb can be restored to its original appearance. It is also possible that the car bulb will not light if it comes loose. So check the connections. It is also possible that the source of the failure is the commodo or the nerve centre. That's another thing to check.

How do you best check it?

All car lights should be checked regularly. So test the lights and indicators when you stop. Do this in a garage or outside and for a better result, wait until it is dark. Also, let yourself be helped. That way, you turn on the switches while another person checks the bulb's operation. If one of your car's headlights at the front or rear is slow to come on, the reason is often a bulb failure. But you only must look a little closer to see if the filament is broken. Very often, a blackening of the bulb means that the bulb is no longer working. When you're done, go through the bulb change. Otherwise, you may be fined. And if you drive at night, you increase the risk of danger to yourself and other road users.
