i got this on ebay and i am very impressed with the quality construction of the Aluminum body, also, seems quite bright and easy to operate. You just push the red lens and it turns on, push it one more time and is fast flash, another push and is a slower flash, you push it once more and it turns off. It mounts very well on my seat post.
I wonder if anyone one else has tried this light before, i also wonder what kind of LED is inside? 1/2 watt led?
