externally mounted back up lights?

Hey guys, have any of you seen a sharp looking set of 2 inch diameter white lights that i can mount to the bottom of my back bumper out on the market? my windows are tinted to the max and it's hard to see back there. Also, they would be good for camping or whatever...my criteria is:
they have to be cheap <50$, and small, kinda plain but good looking, thanks for any imput
