What are the causes of car headlight failure?
1 Answers
Car headlight failure is caused by poor circuit contact. Failure causes: The reasons for sudden car headlight failure include burnt-out bulbs, overheated wires, damaged relays or combination switches, open or short circuits in wires, blown fuses, and poor circuit contact. Solutions: Check if the fuse is blown. If all lights are on, it indicates a problem with the dimmer switch. If the high beam and low beam do not light up when the wiring is connected, the fault lies between the dimmer switch and the headlights or between the dimmer switch and the low beam. Due to prolonged use, the mirror surface (headlight) may age or crack, leading to light failure or insufficient brightness, necessitating headlight replacement.
