I got the bulbs in by going in from the back (engine compartment). On the model of truck that I have, I had to take out the battery tray on the driver's side and that let the windshield washer fill tube move enough that I could get to the bulbs from there. The passenger side, I had to take the top off of the air box and remove the filter.

To pull the headlights out from the front, looks as if you would have to remove some surround plastic for the grille.
