If you install LED turn signals you WILL need either to use resistors or an LED turn signal relay. Personally I would never use resistors so I chose a LED relay. The relay is located under the fairing to the right of the rear seat. So you have to take off the entire backside of the bike, which include the drivers seat and the panels under the drivers seat. Sadly I did not take any pics along the way, but I did want to post up I bought a Universal LED relay from Cycle Gear and it worked great! The one that claimed it would fit any Honda did not fit so do not buy one of those! I had to do this because I installed LED rear turn signals..

I have a set of front LED turn signals in the mail so I will know once we get them if we will have to do any sort of Diode mod like what was required on the 250R.

What's the difference between a relay and resistor? Benefits and disadvantages?

Resistors get HOT the longer they are on they can help the casing off wires, they can melt our plastic fairings.. Also one advantage of LEDs is that they use a fraction of the power of a standard bulb, if you add resistors your kicking the power usa

Resistors get HOT the longer they are on they can help the casing off wires, they can melt our plastic fairings.. Also one advantage of LEDs is that they use a fraction of the power of a standard bulb, if you add resistors your kicking the power usage of the LED back up to what an standard bulb is, im my opinion if your going to use resistors dont change the bulbs haha..

The only advantage is it get the LEDs to work without putting in a new relay haha..

What exactly does a relay do?

I know how a resistor works. it basically burns off the energy that the LED doesnt use so that the ECU thinks it's a regular halogen bulb. resistors run HOT

I am just throwing these numbers out there but the idea is the same. Say the stock turn signal relay requires 10 watts of input to signal the relay to blink. That would mean each of the standard bulbs would be 5 watts. If you turn a signal on you

I am just throwing these numbers out there but the idea is the same. Say the stock turn signal relay requires 10 watts of input to signal the relay to blink. That would mean each of the standard bulbs would be 5 watts. If you turn a signal on you light up two 5 watt bulbs and that creates the 10 watts to trip the relay into flashing. Now swap in 1 watt LED bulb rear turn signals and turn on the turn signals, your front standard bulb is creating 5 watts and your new rear is creating 1 watt so your 6 watts of load will not trip the stock relay into blinking, so the lights will just stay lit and not flash.

So when you install when they call a LED relay, its just another relay that replaces the stock one, but this time rather than the 10 watts required to trip it, it might only take 1 watt to trip it. So you can have LED front and rear signals and in a perfect work it will work. I say that because on the 250R it did not work, there were backfeed issues which required the "diode mod" which is a little more complicated to explain, so that might be easier to just google.

Ahh I understand. So the relay controls the flashing.

I remember reading that some guys find where the oem flash relay is and take it apart and swap out a resistor so that the stock relay recognizes lower wattage as correct. Wonder if this will be p
