I’m not sure of the model it’s older without the deceleration, but it the brake and turn signals model.
I mounted the control module just above the ecu, with Velcro, very small very light. Yes very bright and noticeable!!
WOW. Was just introduced in Jan 2017 and the video was impressive . . . http://www.ohmics.com/projects/
I'm now considering the BrightAssLight.com BAL-10T
I have seen these on Harleys and they are terrific, the brighest I have seen for a dedicated tail light. BrightAssLights.com - BAL-1 Tail Lights, Super Bright LED Lights
Not cheap, but you usually do get what you pay for . . .
I think at this point I am leaning towards an independent control box (flashing brake with deceleration but also wired into brake light circuit) controlling a long bright led light bar mounted up a bit higher on the bike than the license plate. Will also convert tail light and turn signals to leds.
