that LED light when intact is also a powerful led blinky, btw
so pick up an extra one for $5.00 and mount it as a be seen light in combination to the Fenix's
Getting 4 Fenix's, one on the helmet, and three on the bike would make a fantastic setup then have one smaller Power Beam for a flasher would be grand

the power beam is as bright as the BLT Ultra Doppler DX
$45 WTF?
