lol aww.............i'll do my best to answer. i uh...am not exactly 100% sure what you mean by a light. do you mean a seperate light?
if so...not worth the dough!! LOL The reason I say that is bc my DS (the old one - it's blue - LOL) already has a light installed in it and it works PERFECTLY...(not to mention...when you play it at night under your bed sheets!!!!...lol) So yea...a regular DS is fine, man...lol
