Really not a lot available for tail lights.
Headlights, yes. But I can't think of a good website off the top of my head.
Unfortunately, there really ain't a lot of aftermarket lighting available for OBS trucks. And what is, was made for the late model bronco/early 90's lightning market.
Headlights and tail lights off either will fit the OBS PSD's though, might open up your search a bit there.
