LOL I have the same thing on my dash. It's a switch I installed thinking I was going to install fogs. Never went beyond mounting a switch. Good thing I never sell my vehicles; any future owner would have been on this forum asking the same exact thing...
KC is an aftermarket company that makes fog light kits, and has for many years, so I’d assume the switch is from one of their kits and the original owner kept his lights but left the switch to avoid having a hole in the dash. The Toyota 4x4 from Back to The Future had a bunch of KC lights.
