I suppose this could be classified as "Bling" but is more of a safety item. I came across this in the Regs: http://www.austlii.edu.au/au/legis/nt/consol_reg/avsr324/s77.html There's one called the Diamond Star Headlight Modulator which: - Supposedly connects to standard wiring loom - Has a sensor that allows it to only operate by day when light levels are high enough (have heard it will dim in a tunnel). Where to mount that seems to be the hardest part of installation. - Turned on and off by switching the headlight to the opposite beam and back within 1 second - no separate control, default is on when the Bike starts - Also can be hooked up to the Horn so it flashes when the horn is sounded - not sure for how long. Seems like a good idea. I doubt, if I had one, that I'd leave it on all the time but you theoretically can. I reckon it would be useful if Filtering was ever made legal. Turning it on and off might take up some valuable time you need otherwise in some situations. YouTube vid of it in operation. This vid shows other products too. The Headlight Modulator is at the start.
