Open the hood, and in the top right and left corners of the primary headlamps you'll see two pins (L shaped) swing them out (towards the front of the truck) and lift out. This allows you to remove the upper headlamp assembly. You can then remove the lower assembly by pushing outwards on the plastic clip that is hooked into a metal clip. Once it's out you just turn the bulb to remove it.
It's much easier if you unhook the leads to the upper assembly's bulbes so you can set the whole thing aside.
