What are the reasons for the low beam not working?

[ReidMarie]

Reasons why the low beam does not work are as follows: 1. Dead battery: You can check the battery level by pressing the horn. If you forget to turn off electrical devices overnight, the car won't start the next morning, and the low beam won't turn on either. 2. Bulb damage: Ordinary bulbs have a certain lifespan. When nearing the end of their life, the light intensity may not meet standards, and they may overheat until the filament burns out. Other reasons include water entering the headlight assembly after driving through water. When a hot bulb encounters water droplets, the sudden temperature drop can cause the bulb to crack and fail, resulting in no light. 3. Blown fuse: The low beam fuse can usually be found in the engine compartment fuse box or the fuse box on the left side of the dashboard. The fuse specifications are listed on the back of the fuse box cover. Use a specialized clip to remove and inspect the fuse. 4. Fault in the low beam control circuit: There might be an issue with the light control switch. In this case, you can take the car to a repair shop for inspection to determine if there is any abnormality in the light switch control logic.
