I noticed the last couple of times I washed my car there was water in the tail lights. These are not aftermarket ones and Ive talked to the dealer about it. They said all tail lights leak and there isnt anything they can do. What can I do myself to seal them a little better? Silicone?

 

You need another dealer. NO tail lights should leak.

 

Your tail lights should not get water in them. Try to locate where the water is entering your tail lights. Maybe you have a hairline crack or something. What I use to seal stuff like that is RTV Silicone Gasket Maker. Other Silicone sealants should work to.
