his stock headlights take a 9004 high/low beam bulb. i think with the one piece headlights you have to use a h4b bulb or something of that sort…damn near impossible to find btw.
they are h4h bulbs and yes they are a pain in the ass to find, i had the actual jdm headlights in my 92 teg and you can alter h4’s to fit, i just carved off a sticky out part of the bulb base that was not letting the bulb go all the way in and then bend a coathanger in the shape of the metal clip to hold them in, worked perfect, aimed fine.
