for the cheap route, just go to autozone or pepboys or wherever and buy 2 9005 Sylvania Silverstars and do the 9005 conversion (do a search on how to do this conversion)

for the expensive route get a 9006 HID retrofit kit from www.proxenon.com www.suvlights.com www.auto-lamps.com

i suggest getting 4300K or 6000k, the higher the value the bluer the light will be and the bluer the light the less vision you will have on the road.
