I got this link from Warthog. It seems you can retrofit almost anything to LED with those guys.

I changed my navlights to these, I don't know if they will fit your application but I like them better than the Perko's that were there. The good thing is they are relativley inexpensive. I have not got the LED upgrade yet.
