You don't need to remove the front bumper to remove your headlights. Seems kinda silly to have to remove the whole bumper everytime you have a headlight out. don't you think?
All you do is remove the two bolts on top of the head light, and the small push clip in the corner if the grill. (just gives you more room to work with)
Then pull out on the outside corner of the headlight while pushing in on the inner corner. Takes a little manouvering but they will come out.
