I was hoping someone could give me some insight. We went to Cycle Gear today and Juli found some aftermarket signals she wanted. I just installed them and they do not work. These are not LEDS, but just a smaller filament bulb. I tested them on the battery, and the bulbs check good. I also purchased the harness kit which made the install plug and play, double checked polarity at the connections, and I have voltage at the bullet connectors. Anyone have any ideas? The fronts blink fast now, like my Busa does with the LED undertail. But no lights on either signal. The bike is a 06 Katana 750. Thanks for any help at all, I am lost.
