I believe there a few ways to do this. If you check the history there are a bunch of threads covering it. For me, I did the mod where I added new sockets/bulbs to each side of the rear light. Changed all bulbs to LED with the exception of the turn signal bulbs which are used as a ground in the Honda wiring circuitry. That gave me the full running lights. Then I added a Whelen TIR3 strobe wired into the brake light wiring, mounted it in place of the reflector and moved the reflector down towards the bottom of the fender. Thats been working great for over a year now without issue and folks riding behind me remark how much better they can see me.
