What Causes Car Headlights to Flicker?

[SanSamantha]

Car headlights flickering may be caused by poor contact or abnormal bulb quality. Headlights: The main purpose of headlights is to illuminate the road and objects ahead of the vehicle, ensuring driving safety. The high and low beams can be alternately switched as a signal for overtaking at night. Headlights are installed on both sides of the front of the car, with each vehicle equipped with 2 or 4 units. The bulb power is 45-60W for high beams and 25-55W for low beams. Fog Lights: Fog lights are installed near the headlights or slightly lower than the headlights. In conditions of low visibility such as fog, snow, heavy rain, or dust, fog lights serve to illuminate the road and provide signals to oncoming vehicles. The light is mostly yellow, as yellow light has longer wavelengths and good fog-penetrating performance. The bulb power is generally 35W.
