Well, I did find a few here:
http://superlumination.com/otherleds.htmPer the interior bulb guide, that bulb should be an 1895 type... Scroll down to "1895 ba9s bayonet base bulb" and you should see 'em.These look to be the best I've found thus far. I've found some cheesball ones with just one single surface mount LED, like that's going to be of much use. The five led's in these angled the way they are may work out somewhat good....I know nothing about the company, so couldn't help ya there.Are you looking to replace the map light for "accent" light purposes, I take it?
