These fog lights are the ones that were on the early Sport model YJ Wranglers, or could be bought as a Dealer item. I'm not sure if they are still made, But I sure would like to get my hands on a couple of the len's to replace mine. They are a French cut lens and it is a Fox head on the lens. They have a very low and wide pattern for the beam. I also have the covers for these lights.
I had the same fog lights on an 87 ford escort gt, back in 1995 i was able to buy the complete kit from the local ford dealer (it was cheaper to buy a complete kit than buying two lenses), check your local ford dealer or wrecking yard. jjc
