if you're asking about taking off the panel and removing your dome light and/or passenger/drive side lights, you can *or atleast i can on my car*...thats how others change the color of their interior lights
I imagine it must be possible, what's being described sounds exactly like what my SVT has. I don't know how you go about getting one, but the dealer may be able to assist you in ordering the "deluxe" domelight. I must say, however, that it doesn't make that much difference if you're looking for a "spotlight" kind of light, the map lights still spread out into a pretty wide beam of light.
argggghhhh! I KNOW I saw this somehwere before, but I CAN'T FIND IT NOW.
I guess like SVT4ME said, go check with a ford dealer. I don't think that they woudl have any problem ordering one for you, I just can't remember how much it was.
I got my maplights used (in mint condition) off eBay. The guy sold them to me for $12. They are direct plug and play of course. Just unplug the the two plugs, and plug in the new ones and bam you're in business. Very easy to install, and the extra "projection style" maplights are very useful to me. They are good quality, made by Hella too hehe
