Sorry to Take so long to get back to y'all.
You want a Kisan SM-1 to make it work. Â Splices in to you system with no extra switches. Â Takes some getting used to. Â I have the dip switches on the box set to full bright for the running lights and Long Cancel (about 40 flashes.) Â The nice thing is if you remember you can still turn the signals off early. Â Turning on the right flasher 3 times and back to center off in 3-5 seconds turns on 4 way flashers. Â Turning on the left flasher three times turns on the "Test" pattern which is really what I would consider an emergency flasher (as in my wife is going to the hospital and I need to get there as fast as possible). Â This alternates the right and left flasher. Â To get out of four-way or emergency flasher you just turn the turn signal switch back to the right or left until it turns off. In running light mode your green turn signal indicators will "glow". This is normal. 8-)

I had one failure during the warranty period and Kisan promptly sent me a new box (blown diode). Â
I forgot to mention that the box replaces the flasher in the eltronic juction box containing the fuses on the RH side of my 1980 bike. Â Your results may vary.
I also have a Kisan Tail Blazer in my brake light lense:

I installed the  KF-10W-S and had to file it down a bit to get it to fit.  I think this is now the 10W-D but check with Kisan.
Good luck,
