I have a 2001 e53. I have just fitted new led tail lenses. All are working but i have noticed that the top tail light is brighter than the bottom. It looks like the brakes are on but the brake lights are at the bottom with the bottom tail light. Also my car has a 4 pin connector whereas the leds have 5 pins. The box states they are the perfect fit for my car. The original lights worked fine. Has anyone else had this problem. Any help would be appreciated.
