We added a small convenience dome light to the roll bar. This is an LED variety that could probably be used as a backup light. The thing is amazing. Jeffrey sat in the drivers seat and we turned out the shop lights so that we could get a proper angle for mounting, we didn't want to blind any oncoming drivers. No seriously this a well made unit sold by Rear Light Bar made by Dezert-tek cost was $27.79 to the door. We opted to run the wiring inside the roll bar rather than in a flex conduit for a cleaner install. A 3/4" hole was cut into the bar top center and just above floor level behind the seat-belt re-tractor with a Unibit. Hardest part of the whole job was fishing a wire down the roll bar, especially since we had welded in cross bars for the shoulder belt bolts. Trying with just the wire didn't work, so I grabbed some 1/8" dia. cable that was left over from a garage door. Fed it thru from the top and retrieved it at the bottom with a needle nose pliers. Taped the wires fast to it and pulled it back up. A weather pack connector was wired in at the bottom in case the roll bar ever had to be removed and then to the head light switch and a feed off the fuse panel. The head light switch breaks the ground circuit, so the feed is an unswitched source rather than a switched source because we wanted to be able to turn the light on without having to have the ignition switch on accessory or the run position. The possibility of accidentally leaving this thing on is slim due to its brightness.
