If you just changed the bulb of your vehicle's headlight yet you still end up with a faulty one, you'd better check the headlight assembly once again. Chances are you have a busted fuse or bulb socket that needs your immediate attention. If more than one of your lighting components malfunction, check the fuse for any signs of damage. They're most likely busted and you need to replace them to get your headlight to work properly. On the other hand, if only one bulb is acting up, then you need to check the socket right away. To learn how to troubleshoot and maintain a malfunctioning socket, here's a quick how-to that can help you out.
Troubleshooting a Bulb Socket
Before getting a replacement socket, you need to find out if the current one in your car is indeed damaged and beyond repair. Here's how:
Step 1: To begin the test, consult your vehicle's owner's manual to find out which parts you need to remove in order to access the lighting assembly. Using the manual as a guide, carefully remove the blockages, making sure that you don't damage any of them during the process.
Step 2: Once you've removed the blockages, replace your old bulb with a new one. If the bulb suddenly works, then you don't have to change anything else. However, if the bulb doesn't work, turn off the light switch and take the bulb out of the socket.
Step 3: As soon as the bulb is out, observe if the socket is dirty or has accumulated dirt and rust. If it has, you need to clean it using an electrical contact cleaner to make the job easier.
Step 4: After cleaning the socket, reinstall the bulb again and see if it works.
Step 5: If cleaning is not enough, you need to buy a replacement bulb socket. However, before you do that, you can also check the wires behind the socket for any visible signs of damage. If they have tears, nips, or cracks, you might need to replace the wires instead.
Maintaining a Bulb Socket
Sometimes, a bulb may act up due to a dirty socket. To avoid this from happening, here's a cleaning and maintenance guide that you can follow.
Step 1: Before you begin, disconnect the electrical sockets of the headlight and check the wires for any kind of damage. If you find a damaged wire, you might need to replace it to make the assembly work.
Step 2: Next, use sand paper to remove the rust that has formed on the surface of the socket. You can speed up the cleaning process using electrical contact cleaner. Spray the socket with the cleaner and then use a piece of cloth to remove the dirt. It's best to use lint free cloth for this particular step.
Step 3: After cleaning, apply some conductive gel on the bulb socket, making sure that you don't overdo it.
Step 4: Once the socket is clean and free from dirt or debris, reconnect the bulb that you took out and see if it works.
