Hi guys,
Ever since I bought the Z I've noticed that some people stop unnecessarily close behind me, so I recently bought a smoked led foglight from EVO-R (<--good guy to deal with) and a prebuilt flasher relay to get their attention.
I had seen others that built their own relays and while it looked cool I wanted something with a lockout time so it wouldn't flash constantly while stopped. I also needed it to be simple (only 3 wires to hookup) as I'm not an electrical genius. What I bought was a prebuilt relay with 36 selectable modes including "don't flash". The relay also locks out the flash function for 15/30 seconds after you release the brake.

Here it is powered off. It's about the size of a quarter and encased in plastic so it should be very weather resistant.

This is how you select the mode you want. You momentarily jump these two white wires.
How I wired everything. Only three wires to connect.
On the back of the EVO-R foglight I only used black and red. I just tied off the white wire.
Here's a quick video of the relay in action.
The flashing isn't as fast as in the video. My camera just made it seem that way.
