Interesting point about the horn OC if one thinks about circumstance when this would work. As for power to drive a mob of lights, remember these LED's main sails advantage is the lower power draw for the massive output ( some as low as 3w to produce 770 lumen.) Aligned incorrectly they will have a detrimental effect so its more than possible to mount say a light bar of 3700Lmn and some "work lamps" of a spread beam at say 170lmn each on an 80% spread and run the maximum H4/H7 halogen and still come in under a stress level of lots and lots of duel sport and compact tour bikes. Go put that stuff and more on a Rhino and there remain room to run a hot suit and your FLR and more lights.. Mate of mine has FLR set up on his ST. Bowling along one night out the top end of WA and rounds a bend. FLR lights up hundreds of humped up bright" things". Hits the skids and then works out those things are....ant beds . I suspect the 4 driving lights actually means the four forward facing lights. Have you noticed how as the road side singage has improved the night wission with good lights has develpoed into the black hole. Typical is at each end of bridges.
