I installed a brake light flasher unit today. It can be set for several different flash patters to hopefully get drivers attention. It was all plug and play, no splicing. Works good on my RKC, easy install.
Rode 325 miles in the Tri-State area. Went around NWPA, Western NY and Eastern OH. It was for a scavenger hunt by the Erie HD Shop Bike Fest that runs all week.
Have you tested it out yet? Interested in performance.
I purchased the HD version, and ended up throwing it in the garbage.
Don't know about that particular one, but I bought a Tune Trapper and it works great. Not quite as good as the big ugly whip that comes stock, but I'm happy with, FWIW.
