Cateye HL-Rapid 1 Front Light (USB Charge) Quite simply stunning! The Rapid 1 has a high power Led similar to that used in the rear Rapid 3 and 5 with the convenience of USB charge in a compact little unit. The powerful LED combined with Cateye's reflector and opticube lens technology creates a light that is bright, compact and efficient. Brilliant! 4 modes: Constant/RVLR Flash/ Rapid flash/Pulse flash Run-Times: 5hr constant/13 hour flash USB Recharge: 8 hours.
