I installed one on my 2000SE. I decided on the Kisan unit, with the exception of drilling a 10mm hole in the tunnel cover for the photo senser (my choice of location), just plug and play. They even supply text on the federal DOT law allowing the unit on motorcycles, some cops aren't aware they are legal, I asked one. It uses your factory high/low beam switch to turn on and off and is programmable by using the same switch. Most cagers don't like them, opinions are mixed among riders, it does work! First day I put it on, rode to a friends to show him, a car in his housing area pulled out 6' from a stop sign, stopped and let me pass, I even had one car pull over for me on the interstate. They may not like it, but they definately see the flash.
