pulling the headlight assemblies is actually quite easy. on the top of each, you will see 2 clips that need to be removed. they are kinda tricky, but if you look at them, they have "wings" that need to be pulled out and then the clip will slide straight up and off. when you get the 2 clips off, then you will have to reach down towards the bottom, directly behind the light. there is a plastic **** that has 2 "wings" on it, and you have to squeeze them in, and the light will slide forward and out of the truck. the hardest part is definately getting the lower **** released from the light housing. i just changed my lights out a couple weeks ago to install the clear style. the whole job for all 4 pieces took about 30 minutes. hope this info helps.
