What to Do When the Car's Headlights Don't Light Up?
1 Answers
There could be several reasons why the car's headlights don't light up, including severe battery depletion, overheating of wires, or a blown fuse in the headlight circuit. Here are the solutions for headlights not working: 1. First, remove the brake light bulb to check if the filament is burnt out. 2. If the filament is intact, while pressing the brake pedal, use a screwdriver or wire to scrape the positive terminal of the brake light against a metal part to check for sparks. If there are sparks but the brake light doesn't light up, it indicates poor grounding. If there are no sparks, it may be due to a faulty brake light switch or a break in the brake light circuit. 3. To further diagnose the issue, use a screwdriver or wire to short-circuit the two terminals of the brake light switch. If the brake light lights up, it means the brake light switch is faulty and needs to be repaired.
