Bright, long lasting of life of batteries.
A very bright rear light. Uses 2 AA batteries but not had it long enough to see how long they last. However these batteries are cheap to replace and easy to keep a couple of spares. Good system of modes where you can have flash, one LED on or two for a brighter light. Very strong, you cant look directly at the beam for long but this means that it is likely to be seen by tail gaters hopefully! Definitely recommended as a cheap, effective rear lamp.
