Here is a picture of my coach and the left cornering light. If you look at the lower left corner you will see a small white or clear circle. That is the left cornering light. When I activate the left flasher the left amber marker light, under the driver's window, and the left amber light in the headlight assembly flash and the cornering light lights up. Cornering light goes out when the left flashers stop. Same thing on the right front.

I don't think these are real common. Saw them on late 90s coaches mainly.
