OE Replacement: BMW F18
OEM Grade: These modules are original equipment on specific BMW cars which can be confirmed under the "Compatibility" section. Unfortunately: headlight control modules, like most car parts have a rated lifespan and sometimes don't even make it that long. Replacing them outside of warranty is never cheap either! This part usually runs about $400 from the dealership...ouch! Good as New! This replacement module designed to meet/exceed all OE specifications and will be a direct replacement for the factory unit. It is not OEM but fits and functions identically for a fraction of the price! Save Yourself: Most headlight ballasts and lighting modules are rated at 2000 hours of run time and if one just went out, chances are the others aren't far behind. Save yourself the hassle of taking off the bumper again, removing the headlamp, and just replace everything at the same time! Notice: Certain makes and models may use different OEM modules depending on the production date and/or trim level. It is always best to double check and match the part used on your actual vehicle to ensure compatibility. While we are glad to make any exchanges, we are not responsible for mis-information if you purchase the wrong unit.
