I just got a set of THESE
They're just the glass lenses, metal reflectors & bulbs, but they also sell the entire light assembly too. They fit 93-97 Rangers.
If the back part/bracket/housing is still good, these will pop right in place.
They're made in China, but most everything is now.
The only difference in these & the OEM Hella's is these have American imprinted on the lens instead of Hella, the back side is silvery chrome rather than black & the bulb holder clip is a little funky.
If your Ranger has this type of fog light switch... (I forget when the newer style dash came out)
I make a wiring kit that will allow the OEM fog switch to operate pretty much any type of light.
It could be something as simple as a blown fuse, bad connection, bad switch or something shorting out from the missing lens.
