Headlight Ballast for BMW 1 Series F20 Part 63117316145 7316145
Restore precise beam focus to your BMW 1 Series headlight projectors with this direct-replacement ballast unit. Engineered to match OEM references 63117316145, 7316145, 63117304063, 7304063, 63117305238, and 7305238, this component supplies stable ignition voltage to HID projector assemblies, eliminating delayed startups, rain-induced flickering, or total dropout caused by degraded driver circuitry. Designed for the H1 semi interface, it bolts directly into your existing harness without CANbus adapters or software calibration, delivering immediate restoration of factory cutoff patterns for F20 and F21 chassis models produced between July 2010 and February 2015. This aftermarket unit is entirely new and undergoes factory circuit testing before shipping.
Benefits & Practical Tips
Keep projector housings free of road grime and internal condensation to maintain optimal thermal management and prevent long-term voltage instability.
- Inspect your vehicle’s connector pin layout against the H1 semi interface before removal to avoid stress on delicate mounting tabs.
- Replace left and right ballasts together when one fails to keep startup latency and lumen output perfectly synchronized.

Important Reminders
Detailed installation directions are not included; professional automotive electrical technicians are strongly recommended. Always disconnect the negative battery post before accessing headlight components to prevent short circuits. Manufacturing tolerances allow a 1–2 mm dimensional variance, and actual housing color may appear slightly different due to camera lighting and display settings. Verify your exact market specification and chassis build date before purchasing to guarantee correct physical clearance and pin mapping.
