You'll find nice black metal housing tractor lights available from any tractor dealer or NAPA , mount underneath the bed a was in and they can't bee seen untill you turn them on .

They'll really light up behind you and are good for tailgaters too .

I'd like to find a way to mount a switch on the Muncie SM420 tranny .
