from what i know they are standard hella lights. you can buy them from supercheap. from memory they are about 15$ for sealed beams, or 26$? for ones that take H4 globes
get the H4 ones for all 4, and get philips blue vision for all 4, wire them up so they both come on with low beam and high beam (youll need a few relays) then you have an artificial sun attached to your car
expensive exercise though...
