- Faulty Headlight Switch: The headlight switch might be defective, preventing power from reaching the headlight. Check the switch and ensure it's functioning properly.
- Burnt Fuse: Check the fuses related to the headlight. If a fuse is blown, replace it with a new fuse of the same amperage.
- Wiring Issues: There could be loose, broken, or damaged wiring preventing power from reaching the headlight. Inspect the wiring and make sure all connections are secure.
- Headlight Socket: Inspect the headlight socket for damage or corrosion. Clean the socket and make sure it's making proper contact with the headlight bulb.
- Headlight Relay: If your car uses a headlight relay, check that the relay is functioning properly. A faulty relay can prevent power from reaching the headlight.
- Ground Connection: Ensure the headlight assembly has a proper ground connection. A poor ground connection can prevent the headlight from illuminating.
- Faulty Headlight Bulb: Despite changing the bulb, it's possible that the new bulb may be defective or incorrectly installed. Try installing a different new bulb to rule out this possibility.
- Headlight Motor: If your car has retractable headlights, check if the headlight motor is functioning properly and ensuring the headlight lifts up when switched on.
If none of the above steps resolves the issue, seek assistance from a qualified auto electrician to diagnose and repair the problem accurately.
