Which direction is up and down for headlight UD?
1 Answers
Headlight UD represents the direction of the headlight adjustment knob, where D stands for down (low) and U stands for up (high). Below are the precautions for car headlight maintenance: 1. Replacement: Car headlights must maintain good sealing, especially to prevent contamination and damage to the reflector coating. When replacing bulbs and diffuser glass, avoid touching the mirror surface with fingers to prevent leaving sweat or oil marks, which can cause the reflector to lose its luster and reduce reflective efficiency. 2. Regular inspection: Regularly check and adjust the headlight beam to ensure the headlight's illumination distance meets requirements and that the high and low beams are consistent. The diffuser glass should be correctly installed as specified to prevent loosening or displacement and to maintain the vertical alignment of the prism.
