Saw this the other day and couldn't decide if I liked it or not. I have fitted a HealTech brake light modulator ( https://www.healtech-electronics.com/products/blp/ ) which pulses the brake light and definitely gets people's attention. If you call Mike from bikers discount store you can get a forum discount too. http://www.bikersdiscountstore.co.u...healtech-brake-light-modulator-pro-pd-144.php
Most of the time i worry about whats in front.I would have thought most bike accidents are from the front on big bikes. I dont want to diss safety but if you' re on a fireblade and you have someone run into the back of you, maybe you have the wrong bike .
