Original BMW Rear Left Bumper Cover Reflector for BMW X5 (2007–2013)

This Original BMW bumper cover reflector mounts at the rear left of the BMW X5 from 2007–2013 and marks the back corner of the vehicle by returning light from following traffic. It is the left-side piece, which is the driver side, and each car uses one. Part number 63-21-5-A3C-B63 replaced the earlier 63-21-7-158-949. On 2011–2013 cars, BMW applies this reflector only to vehicles built with the M Aerodynamics Package.

Original BMW Parts carry a 24-month parts warranty.

The production split matters most when choosing this part. Earlier X5 models from 2007–2010, including the 3.0si, 4.8i, xDrive30i, xDrive35d, and X5 M, use it in the rear left position. Later 2011–2013 models, including the X5 M, xDrive35d, xDrive35i, and xDrive50i, take it only when the car carries the M Aerodynamics Package, so confirm your car has that package before ordering. A bumper reflector has no bulb or wiring and works entirely by bouncing back the light that strikes it.
