“The instrument cluster LED problem with my 2000 mercedes clk 430 has become more of a problem within the past month. It happens quite frequently now. Whenever I start the vehicle, the gear indicator does not indicate which gear I'm in and the car proceeds in low mode until I pull over and restart it. The safety hazard lies in the fact that I don't check my gear indicator constantly, so if it fails and I don't notice, the low/slow mode that the car automatically shifts into could get me killed on any street where the speed limit is at least 35. …”

Upon close examination all of the wiring inside and outside of the headlamp enclosure was deteriorated. The protective plastic covering over the wires were crumbling and had fallen apart, bare wires had been touching inside of the housing. The wiring on the interior of the housing is not exposed to the elements. The wiring on the exterior of the housing exposed to the elements exhibits the same failure, in that the protective insulating plastic coating is deteriorated and exposed copper wires are touching each other.”
