Yes, sort of, on the back of the challenger 1800 there are 2 drain plugs so I drilled 2" above so the lights would clear the reverse clam thing, then I drilled a hole about the same size, then plugged the lights in snug with marine silicone and a nut screwed on back, and with the wires I tapped in to the stern light wire so now whenever the stern light is on so are the underwater LED lights! All by a switch. Well worth $80 if you ask me.
