NiteRider MiNewt Mini-USB Lithium Ion Bicycle Light $79 @ REI

REI has the NiteRider MiNewt Mini LED Lithium Ion bike light for 20% off or $79.19. Sale ends 9/7/09

Granted, this is only $11 less than Amazon.... but you are buying from REI where everything is guaranteed for life.

This light is unique because it plugs directly into a USB to recharge. Gimmick, perhaps. It eliminates the need to carry the charger with you on your commute (assuming you work in front of a computer) if both out and back are ridden in the dark.

Features:

110 Lumens (or more)
Weight 175 grams
3 hour runtime (On/Off only, no blink or lower power setting)
4.5 hour recharge using the wall charger, USB charge varies (was also 3 hours for me today)
Very easy to mount and move from bike to bike.
Made in USA

Daylight is getting shorter and bike commuters will soon need a good light. While this is not the best available, it is pretty darn good for the price.
