Original BMW AHL Xenon Headlight Driver Module for BMW 5 Series F10, ActiveHybrid 5, and M5 (2014–2016)

Xenon headlights on the BMW F10 5 Series, ActiveHybrid 5, and M5 (2014–2016) with BMW's adaptive AHL lighting rely on this Original BMW headlight driver module to control their bulbs. A xenon bulb cannot run directly from the car's 12-volt supply, so every xenon headlight needs a driver module to start the bulb and keep it lit. BMW names this one the headlight driver module, AHL xenon light, and it applies only to cars with adaptive xenon headlights. The module weighs 101 g (0.2 lb), is made in Germany, and entered BMW production in March 2016.

Original BMW Parts carry a 24-month parts warranty.

This is the current number in a short line of supersessions. BMW replaced 63-11-7-427-607 with it and rates the newer module as retrospectively interchangeable, so it fits cars built with the earlier one, including 2014 and 2015 cars that predate its production start. Earlier numbers 63-11-7-381-017, 63-11-7-408-422, and 63-11-7-409-579 also cross over to this module. If your car carries any of those numbers, this is the part to order.

Common Questions

Can this module trigger a xenon bulb warning?
Yes. A bulb failure warning for a xenon headlight can come from a fault in this module rather than in the bulb itself.

What usually causes these modules to fail?
Water getting past the seal is the usual cause, and the resulting damage is easy to spot on the circuit board.
