	Using diodes is probably an easier way to do make your new signals work than the LED method described below. It should be easier for most people to solder wires and make a ground using a ring terminal than to fiddle with small parts inside the gauge cluster. Another nice feature of this modification is that any cluster will work, so if the cluster needs to be replaced for any reason, the wiring modification will still be on the bike.

	A diode is a simple one-way valve. It only allows electricity to flow in one direction. This will keep the two turn signal circuits separated.

Since there are 2 wires on the bike to connect to the 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.

	The stock EX250 flasher is solid state, but it's fairly simple - just a chip with a cap and a resistor or two. It doesn't use a timer, though. This is why its flash rate varies with bulb load, like an old mechanical flasher. With mechanical flashers, ~~the flash rate is determined by the bulb load. As~~ more bulbs are added, the current through the heater element increases and causes it to heat faster, breaking the contacts faster and resulting in a faster flash rate. The Ninja's solid-state flasher reacts the opposite, flashing faster with the reduced bulb load from lower-current LEDs. Fixed-rate flasher modules (like the new one you're putting in) use a timer to regulate the flash rate independently of bulb loading.

	This is the easy part. You need to replace the ~~thermal~~ flasher that came in your bike with an electronic one. An electronic flasher (aka turn signal relay) will make your flashers blink at the same rate no matter whether they are LED or incandescent. The ~~thermal~~ flasher that came with the bike doesn't work with the low current demands of LED lights. The pictures show the location of the stock flasher.		This is the easy part.

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.

	At the six-connection plug under the headlight, use a paper clip to remove the green and grey wires from the male side of the plug. In stock form, these wires bring power to the "your signals are on" dash light. You are going to splice into these wires. When you do, leave enough wire on both ends to make the splice, ie... make your cut several inches back from the connector.
