This used genuine OEM Audi headlight switch / button (part number 4K1941501Q) was removed from a donor vehicle. It controls the headlight functions and is also commonly referred to as the headlight button. In models such as the Q3 and Q4 e-tron (including battery EV variants), a failing switch may cause headlights to not turn on, remain stuck in one position, or flicker.
