What causes the failure of the right-side low beam on the BMW X1?

[VanMiranda]

There are several possible reasons for the failure of a car's low beam: 1. Wiring issues: Poor connections, loose wiring, or improperly seated connectors may cause this type of fault; 2. Power mismatch: Using bulbs with incorrect wattage specifications during replacement could lead to this issue. 3. Usage duration: In some vehicle models, prolonged use may cause headlight lens aging or cracking, resulting in light failure or insufficient brightness, necessitating headlight replacement; 4. Reflector issues: Deformation, loosening, detachment, or quality defects in the headlight reflector may cause poor light concentration or dispersion, potentially leading to insufficient brightness or unfocused beams.
