The biggest problem that I had trying it mwilson's way was getting the bulb retaining ring to engage the 3 screws on the back of the headlight assembly. Just not enough room to apply even pressure all the way around. Like BMHenry, taking the headlight assembly out is far less aggravating.
The H13 bulb that the 06-09 trucks use does not have a ring. There are tabs made to the bulb, simply twist and pull it out.
You can release the bulb, pull it out a bit and then unplug the harness.
