Headlight problems are easy to fix. Below are the common issues you might encounter and some tips on how to troubleshoot them.
Observe important safety measures before working on your headlights. Make sure the car’s engine is turned off. If you have recently driven the vehicle, wait for the engine to cool down. Don’t touch any metal components and pipes around the engine block to prevent burning your hands.
Beware and be careful of the electrical wirings. Don’t touch or pull the wiring connections when not necessary. Also, don’t use metals to test hard-to-reach wirings. If you are in doubt, call for help from someone with knowledge about dealing with car wirings.
#1 Headlight Flickers
If your car’s headlamps flicker on and off, the problem is the poor connection of the headlight line.
Before making any adjustments, check the lamp battery clamp connections by trying to wiggle each wire gently in the headlight circuit. If one is loose, tighten the connection but be careful not to electrocute yourself. If the entire headlight wiring is broken, you will need the help of a professional to fix the problem.
Another issue that could cause your headlight to flicker is the bulb wattage. Bulbs with too high wattage cause the lamp to flicker. Hence, make sure to use bulbs with the correct wattage recommended by your car’s manufacturer.
#2 One of the Headlights is Not Working
A burned-out bulb is a reason why one of the headlights doesn’t work. All you have to do is replace the bulb.
Take note that in HID headlights, you have to replace both the bulb and ignitor since they are one unit. Thus, you’ll have to look for a good bulb and ignitor to replace the burned-out headlamp.
If the bulb still doesn’t work, chances are the problem is on the wiring connection of the headlamp.
#3 Both Headlights Doesn’t Work
The common problem when both headlights do not work is burned out bulbs. But if both headlamps still don’t work after replacing the bulbs, the issue might be on the power or ground of the wiring connections.
If the likely cause is fuse disconnection and wiring fault, consult the owner’s manual to locate the main fuse for the headlight circuit. Replace the broken fuse with one having the same amp rating. If you are having difficulty fixing the problem, you might have to visit your mechanic for help.
These are only some of the common headlight problems you will encounter. Also, you can learn more here on how to fix these issues step-by-step. However, always remember to follow safety precautions and ask for help when dealing with difficult headlight issues.
