front lights

i was wondering.. i've seen some mustangs 01-03 wit either the Clear lights and i've seen some wit the Black lights.. its there a special package for that? or did the owners bought some after market lights? im asking this because im thinking of getting a mustang instead of 3000gt or eclipse since its WAY too cheap and fast... I would perfer the black lights instead of white because it looks nice. black on black or yellow mustang wit them black lights.

oo yeah and another question. a regular coupe mustang only gets around 20mpg? what the.. at least its regular unleaded gas. im wondering how to get more mpg? some people said driving at 55mph max and not revving alot will get u to at least 25mpg. is that true? or can only mods help me?
