BMW 7409739 7427616 7440883 7396129 7401747 LEAR TMS LED Headlight Driver module ballast.

LEAR TMS LED Headlamp driver module is factory fitted on BMW F25 X3 Facelift LCI and F26 X4 cars with adaptive full LED headlights.

Adaptive LED headlights mean that when you turn your steering wheel, xenon lights move to the same direct as well.

Driver module needs to be replaced when you are getting various malfuction errors such as vertical aim failure error, low or high beam can't move up or down, but just stays looking down and not move up, red headlight icon, headlamp warning light malfunction error, AFS adaptive headlight failure error, LED Angel Eyes Daytime Driving Lights don't work at all or flickering, front turn signal (indicators) don't work.

There could be other type of faults or errors when headlight module fails.

No need to buy whole headlight housing as BMW dealer suggests, just replace LEAR TMS module and it will fix all of these issues.

Each headlight uses one TMS LEAR module.

It could be fitted on the left or right (passenger or driver) side headlight.
