Three problems related to headlights have been reported for the 2007 BMW 550. The most recently reported issues are listed below.
The insulation wiring deteriorated causing the passenger headlight to stop working while driving on the freeway ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.
Wiring in headlight assemblies shorts out because of degraded defective wiring insulation. Headlights can immediately fail while driving at night. Passenger side headlight failed.
Was replacing h7 headlamps and discovered all of the insulation on the wiring inside both headlight assemblies had disintegrated and both assemblies contained multiple bare wires. This could result in a short or blowing a fuse when driving making headlamps stop working. Could easily cause an accident. Or car could catch on fire due to short circuit. I have googled this and found many many similar complaints. A recall should have already been voluntary on BMW USA or forced by the ntsb. Extremely dangerous situation.
