There are two sizes for the spotlight. I think you want the par36 but I cannot tell exactly from your pic. Can you measure the glass from the bulb then I can answer better.

I have one of these spotlights as well. Ive seen several of them but I noticed yours and the others come through the pillar. Mine comes through the cowl with a trim piece that looks specific to our trucks.
