The intermittent dimming and brightening of the headlights on a 2006 Honda City is caused by a blown fuse or a short circuit in the bulb. Here are some precautions for car headlight maintenance: 1. Replacement: Car headlights must maintain good sealing, especially to prevent contamination or damage to the reflector coating. When replacing bulbs or diffuser glass, avoid touching the lens with your fingers to prevent leaving sweat or oil marks, which can cause the reflector to lose its luster and reduce reflective efficiency. 2. Regular inspection: Periodically check and adjust the headlight beam to ensure the illumination distance meets requirements and the brightness is consistent. The diffuser glass should be correctly installed according to specifications to prevent loosening or displacement and to maintain the vertical alignment of the prism.
