Hot Rods Fog lights on 49 Chevy deluxe- identification help

I just picked up this 49 deluxe today. It’s all original and unmolested (so far) and it’s pretty rust free for being up in N Idaho. Also, was super stoked when I found the fender skirts buried under the back seats. (Been working on getting this car for a while)
Anyway, I have been stumped trying to figure out these fog lights. I can’t find any other 49’s that have these. (All I’ve seen are the ones that bolt on farther out on the bumper)
They look factory and are set into the grill.
Anyone know anything about these?

 

They are an aftermaket fog light, should be a name on them

 

Yep aftermarket and maybe intended for a truck originally.
If that is an R license plate it spent part of it's life in Benton county in Washington.

That's how we used to tell if guys were local to a county or from out of the area.

 

Thanks guys. Weird that I can’t find anything on these online. I’ll have to pull one off to see if there is info on the light.
They are so much cooler than the factory ones! They fit prefect too, they follow the curves of the grill perfectly.
