i really like the superflash...
late at night drunks will probably think your an alien visitor or something and won't come near you.
on a recent trip across PA (we rode a lot at night) i got lots of room from people when i with that thing on.
the "flash" is so bright it eventually annoyed the hell out of everyone i was with when i wasn't in the back (it can also be set to normal blink).
it is bright, annoying, and it will get peoples attention! i wouldn't want to stare at one for hours, that is for sure.
