Just got through installing Emergency Flashers on my roadstar. Cost me about $15-$18. all you need is a inline fuse holder,a 552 flasher,some wire and connectors, a few splicers and a double pole single throw toggle switch. I spliced into the blinker wires right under the seat. they work great! I ride with the Patriot Guard so this will come in handy! I mounted my toggle under my left leg on the side panel...
