Paul, I replaced my passenger side docking light last year while in Indio, CA.

I looked numerous places like auto parts stores, NONE had one, but finally found it at the Marathon facility. I don't have the p.n. with me but will be in the bus tomorrow if you still need it?

Also interesting enough, I bought two (2) and one of them was bad out of the box. Marathon Ft. Worth changed it out for me, for my spare.
