If that's a Colorado Carefree unit, then know that I bought a plain-jane set off Amazon. Exterior rated. But cheap. Pulled the old ones out, slapped the new cheapie in and had to do a little rewiring. But they work. So much brighter than the originals too!
IIRC Carefree wanted something like $50, maybe closer to $100.
I think I bought the replacements off Amazon for under $15.
