not so much. ever been in bum-f*ck on a new moon? good luck with an open door.. it works in lit area, and the city.. and for a little insurance, why not have reverse lights?
not really the ideal setup but it works:
goto walmart, buy a pair of cheap ass fog lights. (guess you could use both.. buddy and i only used the one out of the pair.)
mount the some-b*tch up under the rear bumper and splice it into the reverse lights. when you reverse.. you have light. make sure to tuck it up under the bumper good enough so it's not hanging. you only need to have about 5-6ft behind you lit up, unless you need more..
did this to a buddies truck, no pics but must say works pretty good. planning on doing something similar this spring to the gp.
