Yes. I added both rear and forward facing 55 watt Halogen lights to the ROPS.
I purchased 4 of the same brackets that hold the optional rear work light (K2561-96250; PLATE WORKING LIGHT, brackets were $$$), made my own u-bolts out of 1/4" all thread and mounted the lights on the ROPS.
I then purchased 1/2" slit-convoluted sleeving (the same stuff all the wiring on the tractor is already in) from McMaster Carr supply. I installed three 14 gauge wires in the sleeving, ty-rapped it to the rops and routed the sleeving to the seat area and then under the tractor to the front area somewhere around the oil filter. The sleeving was ty-rapped all along the way to keep it secure. Then routed it through the existing wiring hole in the firewall.
I picked up electric from one of the switched spares on the fuse box. I mounted a marine grade SPDT (single pole double throw) switch on the left side of the tractor console. I also mounted two 20 amp enclosed relays either on one of the support brackets or the firewall (can't remember without looking) and did all of the wiring. The way it is set up with the SPDT switch, I can only turn on the front or rear light at one time. I figured I would only be going in one direction at a time when using the lights. I had the high amp alternator installed when I purchased the tractor.
Bottom line, after the long winded explanation, you can run wiring from the back to the front of the tractor with some effort.
