I am just wondering wut kind of bulbs do i replace my headlights with on my 04' predator?

Is there any kind of the cool blue bulbs for it like for autos?

 

Last I heard, the bulbs were specially made for the Predator, and people weren't having any luck getting others to fit. Things change though, maybe someone will pipe in with a solution. If you want some very compact lighting additions, the Trailtech HID's are very nice pieces. Other than the 8" Baja Designs "lazer", the Trailtechs were one of the most impressive lights. They ranked right up there with an HID unit from Hella.
