Shortcomings in the processing of the headlights I could not tell. The installation was not problematic, however, the additional wiring harness has been omitted to connect the parking light. The parking lights work so far but still fine. However, my E39 has no on-board computer of possibly may give an error when the side lights, when the wiring harness is not used. If the harness is used, one has to tap directly from the battery in the engine compartment plus and minus. This, however, is in the trunk .... Lamps were included except for turn signals. In the light setting by Austrian motorist club there was no complaint in the headlights.
