  2. Stock taillight, aftermarket signals
  3. Integrated taillight, stock signals
  4. Integrated taillight, aftermarket signals.

The relay comes preset to 85 cycles per minute. You can alter the flash rate to make it faster or slower. If you slip off the grey cover you can access an adjuster that will enable you to change the flash rate to your liking.

INTERNATIONAL BUYERS: Please make sure your bike uses a 2-pin relay for the signaling system. If your bike has hazard lights it may need the 4-pin relay. Please also note the pin configuration and make sure it matches what is on your bike. IT IS YOUR RESPONSIBILITY TO VERIFY FITMENT BEFORE MAKING YOUR PURCHASE.

Too bad the shipping to Canada costs twice what the relay does.

This customer purchased the item at our site.
Relay works as expected, I only have one gripe. See disadvantage, TST if you can help resolve this, please email me.

Advantages: Super easy to install, no instructions needed if you have any semblance of a brain. Cheap too, and easy to adjust using the screw

Disadvantages: If you want to modify the flash rate, the PCB will get stuck. I pulled on the red plug and that should release the PCB and male plug, only the plug came with. No big deal grab some small needle nose and GENTLY pull the board out. Adjust and insert by hand, this is not my issue. My gripe is that when turning on the signal, the starting state is off. I'd prefer my blinker come on when I flip the switch, not have to wait thinking "did I use my blinker?". It's also bad for changing lanes, I have to sit in my lane for a bit after flipping my blinker switch before turning otherwise my blinker won't fire since it waits. I'm all for fun and safety, but this seems to take away some of the safety.

Purchased this relay to adjust the speed of the aftermarket LED signals on my '15 R3. The one relay brought the speed back down to normal for fronts and rears; plus it was incredibly easy to install. Awesome, awesome product.

Advantages: No need to wire-in resistors; completely plug-and-play

Disadvantages: Yeah...I got nothin'

Well it works exactly as described out of the box. Using this relay with flush mount front signals on my 09 FZ6R. I'm absolutely happy and now I thinking of adding a set of led rear signals.

Advantages: I works and you can adjust the flash rate.

Disadvantages: It doesn't come included with all led signal kits.
