Good evening,

I am having an issue with my 2008 750i. There are two rear tail lights on the trunk and only one is working. I took the one that was not working off the vehicle, cleaned the harness connectors after noticing it had some corrosion on it and also noticed a small amount of water in the tail light. The issue is with the LED lights not working, not with the bulbs. Once I put it back on the vehicle it worked, but it is very dim. Not sure if it is not making enough ground contact or what the issue is. If anyone has advice on this issue I would appreciate it.

Thank you
