My LED turn signals don't work right: Difference between revisions

Since there are 2 wires on the bike to connect to the (part #FE218BH) flasher relay, most any 2 wire electronic flasher should work for the Ninja. You should be able to find one at your local auto parts store. Maybe. If you get a blank look when you ask there, try one of these:

The way the stock flasher works is mechanical. There's a small piece of springy metal in the relay body, and as it heats up from current flow it flashes the signals. Mechanical flashers will increase or decrease in rate as voltage or current changes because the springy metal bit heats up at different rates ... or doesn't heat at all, as with LEDs. LEDs draw significantly less current than incandescent bulbs, so the flasher relay never heats to the point where it 'breaks' the circuit. Electronic flashers are designed so that they have a fixed rate of flashing, regardless of voltage or current. They do this by using solid state devices like transistors to do the job the springy metal bit used to do.
