Now I can see! My tractor of course came with head lights but you need more for driving around at night don't ya. My Bobcat had two leads off the back I found was a 20 Amp fused circut for extra lights. I powers 3 lights well. I don't quite know what amp lights they are (11$ rubber mount lights at NAPA.) I installed a switch because power was always on when ingnition was on. One light in back two for each side.
