宝马7系F01/F02 大灯安定器 63117316213 AHL驱动控制模块

Is your BMW 7 Series (F01/F02) experiencing headlamp flicker, one-sided headlamp not lighting, or AHL (Adaptive High Beam) function failure? This is usually due to aging ballast or AHL driver control module, which cannot provide stable power or control the lighting direction. Normally, this module converts low voltage to high voltage to drive Xenon lamps and automates headlight angle as the steering wheel turns, improving night driving safety. OEM number 63117316213, fits BMW 7 Series F01/F02 (2008-2015) and some 5 Series F10/F11. During installation, disconnect the vehicle power and ensure the module-to-lamp socket is sealed to prevent water ingress; also check headlamp bulb condition to prevent damage to the new module from a faulty bulb.
