Hey I guys I would like to add lights onto the back of the truck so I can see more when backing up. I have heard stuff about KC's, should I get two of these or only one? Also I do not have a load warrior and I would like to just instal these onto the back horiz. bar but if possible would like to be able to push them down so i can get a kayak off and on without hitting the lights, is this possible? also, I would like these to come on when i go into reverse but also have another switch, where have you guys put this switch (03) and what after market switches are out there? Thanks
