i'm all for tailights that sear the retinas of inattentive drivers.
a few years back when i ws riding to work every night (nightshift) I got so pissed off at being almost hit so many times from behind, that i mounted an old nightsun team issue behind my seat, with TWIN 50 watt (prejector bulbs) halogen narrow spots , and custom red glass lenses in place of the clear glass lens. I had a 10 amp hour SLA on the rear rack to power just the taillights. Very effective, you could see it from over 6kms on a straightaway , even with fog.
