i mounted rock lights under my toy, i just went to wal-mart and picked up some lights that came with the wiring harness. 2 lights and wiring harness for like 14 bucks. but if you want to use tractor lights a good idea to do is go to auto zone (if you have one) and pick up an auxilary wiring harness with relay, wire, and a switch. for about 6 bucks.
