How do you fix low beam headlights not working

Most people use their headlights when it is dark. Sometimes, you might work late at night or have to take your kids to school in the rain. When the headlights don't work, you can't see and other drivers can't see you. This could be dangerous and make driving less safe for everyone. If your headlight is not working right, check out this guide.

Headlight Switch

Most cars have lever switches on the steering column that control the high beams. These switches get used a lot. They might wear out and break. That is not something we see very often, but it can happen. If you think this has happened to your lever switch, you will know because it may stop working well or start feeling loose or broken. And if you're not sure, go to your local car dealer for a factory-trained person to check it for you and fix what needs fixing.

Headlight Sockets

Headlights on cars often have two bulbs. Over time, the socket can become corroded and the connection to the headlight bulb can be compromised. If you have a bad ground or other issue, this will happen. This means that if one headlight goes out, both will go out because they are wired together on some cars. But high beams don't usually stop working even when low beams do because they use a different system of wiring.

Headlight Wiring

Almost any electrical system will not work if the wiring is not correct. This is true for the headlights on your car. If there is a problem with the wiring, like if rodents have chewed on it, then the headlights might stop working. If you are familiar with how to use a voltmeter, you can check to see if there is power going to the headlights.

Headlight Fuse Or Relay

All the electrical systems in your car, like the headlights, are protected with fuses. These are designed to break the circuit if too much power comes through them. This protects all the components on the circuit. If a headlight fuse blows, it could cause the headlights to stop working. 

Most headlight systems are also designed with a relay that switches power between low beam and high beam headlights. If this relay goes bad, it could allow power to go to the high beams, but not to low beams.

Headlight Bulbs

The most common reason why a car's high beam headlights work but the low beams don't is because the low beams are on more often than the high beams. The bulbs usually burn out more frequently this way. Some cars have entirely different bulbs for the high beams, and other models have headlights with two different filaments. If your low beams aren't working but your high beams are, we check the bulbs first.

If you are thinking of replacing the headlight bulbs yourself, it is important to know the right way to do it. This is often the difference between a successful project and having to spend more money on headlight bulbs. Article provided by
