Based on the lack of removable molding around the headlight, I am assuming that my truck's headlights are meant to be removed from behind. I think the owner's manual called for H4/9003 bulbs. Sadly, the James Danko service manual and the electrical service manual recommended on this forum seem to have nothing on the headlights. I didn't see the wiring harness or anything useful under the dash, so I am guessing there is some kind of panel in front of it. The only videos I could find were for a completely different headlight configuration, that had external screws and a gray bezel around the headlights. Has anybody found a video for this configuration of headlight, or otherwise know how to replace the bulbs? They're not bad yet, but we don't really have streetlights where I live, and you really need LEDs to see the deer before you are right up on them.
Oh crap, I'm probably late to need as well. Apologies for not seeing your original post. Here's another video of headlight removal.
