a few days ago I noticed a bit of water behind the rear passenger side tail light cover, the next day the tail light wasn't working. been really busy so I haven't really had time to check anything yet so I was wondering if it could just be a blown fuse maybe (the front passenger side still works, just the whole rear unit is out). I'm assuming I'll probably need to replace the light unit as the cover is a bit loose, hence the water in there lol.
