Looks like a winner.
You can do that yourself by adding a back off brake alert. I already have one on my bikes.Someone get ahold of these guys at GOMoto and tell them to sequential from the bottom up on the turn signal portion of these tailight assemblies. They would be much easier to spot if you see blinking from lower corners up to top. When moving away from traditional signal mounts you need to set it off where someone following not paying attention will see the oscillating effects of the sequential turn signal. To me anything for safety built into a custom item is beneficial to rider, passenger and the person following.
