Car Lights Not Working

Every month, hundreds of accidents occur in many cities all over the world due to faulty lights. These can be avoided if we give a bit more attention to maintaining the lights in our car.

Tail lights

First we will be talking about brake lights and the three main ways a pair of tail lights can have issues are as follows:

  1. The brake lights don’t work at all.
  2. They stay on all the time.
  3. Or they operate sort of dimly, so you can’t tell the difference between the brake lights and the actual taillights.

To find and solve any problem related to the car’s lights, the following measures can be opted step by step:

  • To inspect this problem, the first thing you can do is remove the bulb from the holder and check that the filament inside is not damaged or relocated.
  • If there isn’t an issue with the above-mentioned point, the next thing you would want to check is whether the holder is working properly by receiving any power and putting it through to the bulb. And this can be done by using a test light.
  • Another item that needs to be checked is the wires and connections to have no corrosion or loose connections.

Switch

If you’ve gone and tested all these points out and still haven’t managed to resolve the issue, you can move to the inside of the car towards the pedal, where the switch is situated.

  • Firstly you can make sure that the connections on the wires are sturdy.
  • Here you’ll also be required to make sure that the switch has a proper flow of power through its terminals. This can be done by connecting a Multimeter to the terminals and checking the readings being shown in the Multimeter display screen.
  • After this, make sure that the wires are connected back properly.

Fuse Box

Lastly, you can move to the front of the car and under the hood, where you’ll have to make sure that no fuses are blown.

  • The initial objective will be to locate and access the fuse box of your car.
  • On opening the fuse box, what you’ll be looking for any blown fuse related to the lights. A blown fuse can be easily distinguished by taking a look at the element, which is in fine shape if the fuse isn’t blown.
  • You can then replace the blown fuse if any.

Headlamps

Same measures can be taken for the headlights, by checking the following:

  • Make sure that the bulbs have no issues such as broken or faulty filament.
  • Check all the holders for any sort of losing connections or corrosion at the contact points.
  • Go through the fuse box and confirm that the fuses for the headlamps are not blown up or damaged.

Alternator

Another common issue faced by your car’s lights can be due to problems with your alternator and/or ground wires, which may cause flickering in the lights, at the front and rear and even inside the cabin.

After addressing the above-mentioned matters, and solving these issues, you will most probably get rid of all the problems related to the lights of your car.
