I found a lot of diferent stuff for the backlight on this website
Twenga - US Price comparison site, shopping guides, user reviews, coupons, they hav tons of stuff from different websites etc..
And for the lights you have to be carefull, i know that this side of the pond (aka Europe) there are special regulations for the backlights.. I'm not sure how it works in the States, but here theyre kind of a pain in the arse
