goathead said:to change the low beams, you have to remove a screw from the fender-well and change it that way. sounds difficult, but actually is very easy. for high beams you change it in the traditional way. you dont actually have to remove the whole assy. in case you dont know, be sure not to touch the bulb itself while putting it in. the oil from your hands can affect the life of the bulb. if you did know that, disregard. for lots of info on TITANS/ARMADA go to www.titantalk.com .
also, contrary to what chimmike says, they are different bulbs.
