So here is what I put in my jeep tj
http://man-a-fre.com/pa/ipfx51.htm my headlights were brutal before put these in and there are the best!.... They are extremely bright but on low beam it has a cut off to keep the road bright in front of you but not blind any other drivers .
If the link doesn't work or you want to learn more hey are IPF X51 fatboys they are an offroad aftermarket bulb you won't find them in a store have to order them in ( I tried lots of bulbs before settling on this one never tried HID though)
