What to Do When Car High Beams Don't Work?
2 Answers
The following is an introduction and solutions for when car high beams don't work: 1. Poor contact in the headlight power line socket. In this case, you can walk to the front of the car and tap the non-working headlight cover. If the headlight turns on momentarily, it confirms a poor socket connection. Simply unplug and replug the headlight power line socket to resolve the issue. 2. Check if the fuse is blown. When the high beams don't work, check whether the high beam indicator light is on. If it is, the fault lies between the terminal board and the headlight. If not, the issue is between the terminal board and the dimmer switch.
I've been driving for decades and often encounter issues with high beams not working. Most of the time, it's a burnt-out bulb or a blown fuse. First, check the fuse box near the engine compartment and try replacing it with a new one. If that doesn't work, check if the bulb filament is broken—just buy the same model and replace it. If none of these solutions work, there might be a short circuit in the wiring or a faulty relay. Avoid tampering with the wires to prevent electric shock. In such cases, pull over immediately, turn on the hazard lights, and avoid driving at night to prevent accidents. Remember to inspect the headlight system every six months as a preventive measure. Safety always comes first—never take it lightly.
