Original BMW AHL-Xenon Headlight, Left, BMW X1 E84 28i, 28iX, and 35iX (2012–2013)

BMW's left adaptive xenon headlight assembly, 63-11-2-993-501, is the Original BMW front light unit for 2012–2013 BMW X1 E84 models equipped with both xenon lights and adaptive headlights. BMW calls it the AHL-xenon headlight, left, and ties it to two factory options, xenon light (S522A) and adaptive headlights (S524A). Adaptive headlights turn the beam with steering input to light the road through a bend, and a headlight assembly brings the housing, lens, reflector, mounts, and adjusting units together as one unit. BMW gives the weight as 3.4 kg, or 7.6 lb, and production of this number started in March 2011. It is sold as a single headlight.

Original BMW Parts carry a 24-month parts warranty.

Two details decide whether this is the right headlight for a given E84. The first is side, since this number covers only the left unit. The second is equipment, because BMW specifies it for cars that carry the xenon package and the adaptive function together. An X1 missing either option sits outside this part's fitment, so the option codes in the vehicle's build data count for more than the model name. Engine and drivetrain do not change the part within its fitment, as BMW uses the same number on the rear-drive and all-wheel-drive versions.

Common Questions

Will this headlight fit an X1 with halogen lights?
No. BMW specifies this unit for cars with xenon light and adaptive headlights, so halogen-equipped X1 models fall outside its fitment.

What are the signs that a headlight assembly needs replacing?
A cracked, delaminating, or damaged lens calls for replacement, and the headlight sits at the spot on the car most exposed to road debris. Condensation inside the housing points to a failing seal or a crack, and a damaged or loose assembly can leave the beam out of alignment.
