BMW 330i Corner Lights
Reasons for Your BMW 330i Corner Lights Failure
Part of what makes your BMW 330i stand out is its corner lights. However, it can't be denied that these lights are held more importantly for the safety it provides than for its aesthetic benefits. Also called as side marker lights, they basically serve as signal lights so that other drivers would know when you are about to turn left or right. These additional lights increase the visibility of your car especially at night, allowing other motorists to spot you easily and avoid accidents. Usually, your BMW 330i corner lights fail due to electrical issues. Here are tips to find out why they malfunction:
You may notice the corner lights to be working intermittently or illuminating poorly. To figure out the cause of this problem, access the bulb and inspect it for damage. If the filament is broken, the bulb is definitely burnt out and needs to be replaced. Also, check the bulb and its socket for corrosion. Depending on the damage, you may choose to clean or replace the bulb and the socket. Be careful when installing a new bulb, though. Be sure not to touch the replacement bulb with your bare hands. Use a cloth in handling it.
Another possible cause of your corner lights malfunction is an inadequate supply of electric current. Test the positive terminal of the bulb socket for low voltage or poor ground. If the power is really low, you would have to trace the wiring and look for fraying or corrosion. Repair or replace the damaged wire as needed.
Sometimes, the issue could be zeroed in on electrical connection problems. Check if everything in the headlight assembly is properly and tightly aligned. Watch out for the bracket holding the harness and the connector because this component can loosen over time. As a result, the headlight assembly, which includes the corner lights, would no longer lock in correctly and connect properly, causing the corner lights to fail. Replace the bracket if it has already worn out and make sure that the corner lights, together with the whole headlight assembly, are fully inserted when you reinstall them.
