What Causes the Failure of Car Headlights Not Turning Off?
1 Answers
Car headlights not turning off is due to an open or short circuit in the headlight switch wiring or an incorrect signal from the light and rain sensor at the front windshield. Here are the precautions for car headlight maintenance: Replacement: Car headlights should maintain good sealing, especially to prevent dirt and damage to the reflector coating. When replacing bulbs and diffuser glass, fingers should not touch the mirror surface to avoid leaving sweat or oil marks that may cause the reflector to lose its luster and reduce reflective efficiency. Regular Inspection: Regularly check and adjust the headlight beam to ensure the headlight's illumination distance meets requirements and the high and low beams are consistent. The diffuser glass should be correctly installed as specified to prevent loosening and displacement, maintaining the vertical alignment of the prism.
