Original BMW Left Taillight Assembly, Side Panel Mounted, BMW X3 (2011–2017)

For the left rear corner of the 2011–2017 BMW X3 (F25), this Original BMW taillight is the lamp assembly BMW fits in the left side panel, providing the rear lighting on that side of the vehicle. BMW's name for it is the rear light in the side panel, left, and the number has been in production since December 2010. The assembly weighs 1.2 kg (2.7 lb) and comes as one light for the left side only. It is made in Germany and supplied new and unused. A taillight housing is sealed to keep water and road dirt away from its lamps and electrical contacts, which is why a broken lens or damaged housing is a reason to replace the whole assembly.

Every Original BMW Part, this light included, is backed by a 24-month parts warranty.

This light is for the left side only. Choose this light when the left rear corner of the car is the one being repaired. No earlier number appears in BMW's parts data for this light, and BMW still shows it with open-ended production.

Common Questions

What does side panel mean in the part name?
BMW names this light for where it mounts, in the left rear side panel of the body.

Why does water collect inside a taillight?
Water gets in when the housing is damaged or no longer properly sealed. Once inside, it can corrode the electrical contacts and wiring and leave the light malfunctioning.
