Please help my 2017 Jaguar XE Right lights and tell lights are not working properly. We noticed the light assembly was halfway filled with water and after removing assembly and replace the lights that's when the lights stopped working. The trunk light Which is part of the brake light assembly with a trunk lid closed doesn't work at all and the brake light and led light is very dim and halfway works. I swapped the assemblies from one side to the other to see if it worked on the other side and it worked fine. I've checked all the fuses and they all appeared to be working and in good condition

 

Any reason for posting this twice in 15 minutes ?
You need to check you have 12 volts for each of the lights at the supply plug where it goes into the light unit. From what you say, there may be a wiring fault somewhere.

 

I didn't mean to post it twice and I could not find the delete option after it was accidentally posted a second time
