I don't think I'll ever 'get' the strobing brake lights [or headlights for that matter].
I disabled all the fancy stuff on my CustomLED. I find it in itself can be a distraction for people who don't understand what's going on (and there's plenty out there behind the wheel).
I like to manually communicate with my rear brake [tapping].
whether people see it or understand is completely on their part of the social 'road-way' contact we all enter when we get behind a vehicle.
if there's one thing I learned when working in the 'safety' industry is that NO matter what you do - if someone is not paying attention, no amount of flashing/blinking/colours/sirens will stop them from smashing into things. I've even heard people say that the flashing lights themselves were a distraction and they fixated on them.
I've seen people smash into cop cars, ambulances, barrier trucks, construction signs, roadwork signs, school zone signs, other cars [all flashing] - when someone is distracted behind the wheel/bars/handles/whatever, everyone is in danger. NOTHING will stop them except themselves.
if it works for you, it works for you.
just make sure that you're not sitting there thinking "oh yeah, that's bright as all hell, they'll see me now, no matter what" - because THEY WON'T.
