I had one burned out tail light bulb on my 2000 TJ so I bought a full set of 4 bulbs so that I knew they we all of the same vintage. When I was replacing the bulbs I noticed some grime in the light housing and that the likely problem was the dried and cracked lens gaskets. After calling the dealer, searching this forum and the internet, I've found that I can get the gaskets, but only if I buy the lens as well. My lenses are fine. Where can I buy just the gaskets?
