What are the reasons for car lights not working?

[SanJocelyn]

The reasons for car lights not working are: 1. The car light bulb is burnt out; 2. Poor contact in the car light wiring; 3. Damage to the car light relay or combination switch; 4. Open circuit, short circuit, or break in the car light power line; 5. Damage to the car light fuse. The types of car lights include: headlights, fog lights, brake lights, daytime running lights, and hazard warning lights. Precautions for using car lights are: 1. Turn on the low beam when driving at night; 2. Do not use the high beam when a following vehicle is driving close to the vehicle in front in the same direction; 3. When passing sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic lights at night, alternate between high and low beams to signal.
