Trailer Hitch Cover

I have been looking on the net, but my Google-fu is weak today. I am looking for a Rams Trailer Hitch Cover, and I can find lots of those, but I want the one that plugs into your trucks electrical system so it lights up when the vehicles lights are on. This would specifically be for a 2 inch trailer hitch.

Any ideas?

Here is a (Dodge) Ram lighted cover.. Dodge Ram Ligthed Hitch Cover

As for a St Louis Rams lighted cover, I don't see one either..

Thanks, but that would look a little funny on my Tundra Crew Max...
