What are the reasons for the sudden failure of the Tucson's low beam headlights?

[MacMorgan]

Reasons for the sudden failure of the Tucson's low beam headlights: Dead battery: You can check the battery's charge by pressing the horn at this time. Bulb damage: Most bulbs have a certain usage cycle. When they are nearing the end of their lifespan, the light intensity may not meet standards, and they may overheat until the filament burns out. Additionally, there are other reasons such as water entering the headlight assembly after the vehicle goes through water, causing the heated bulb to crack due to a sudden temperature drop when it comes into contact with water droplets. Blown fuse: Most low beam headlight fuses can be found in the engine compartment fuse box or the fuse box on the left side of the dashboard. The fuse diagram is usually located on the back of the fuse box cover. Use a specialized clip to remove and inspect the fuse.
