well, my mods are nothing compared to the stuff you do, but i only need a flashing light to satisfy my homeowners board in order for me to snowplow/snow-blow the roads here.
I was looking at the mini justice bar and the responder series, but i really didn't need that much light bar to get in the way when I'm working under my overhangs and eves.
with this bracket i built, i still have clearance to run the horse corrals and under the eves, even with a slight increase from the packed snow.
I found some lighted switches that fit in the existing blanks on the side panel of the tractor, and there was already a spare 10 amp circuit there that i tapped into. I ran the wires inside the trim cover piece and out over the rear window. I HAVE to remove this light during summer months as i work in the trees, and this light is too much $$$ to smash on some branches. Its amazing how bright this light is. Whelen sure turns out some amazing products.
Anyways here a are few pics. I just used scrap metal from my growing pile to build it, and plasma cut the beacon base.
