They fit 2R trucks only. The fog lamps are pictured in the 2R accessories catalog and listed in the early 1950s accessories price books. The whole kit is listed in the 1950 edition of the 2R parts book, and the component parts still appear in section 0631 of the 49-56 parts book. By the time this latter book was printed, the kits were no longer being offered and most of the parts were NLA.
I had a set mounted on my 3R6, but had to move them outboard on the bumper to avoid having them hit the prow of the 3R grille.
