So it happened on my e39 as well.. The right headlight just would not shut off. Even if the car was turned off and locked, the right headlight was still on. It’s an well known problem, but it seems the components are getting harder and harder to get ahold off. The first replacement component, BTS 426 L1 (Farnell is out..) The suggested alternative components were’nt availiable to swedish non-company customers (VN21 availiable from ST. VN21). Instead, the only component I could get ahold of was the BTS426L1 surface mounted (see product image). This component was not supposed to be mounted this way, but mine have been used this way some 600 km’s now and seems to be working.

Have a look at the images from the operation.

Allright, the process should be visible on the pictures..
