NiteRider

I would like to give this light 5 stars like everyone else, but the mount strap is too short. I was able to stretch the strap and get it to hook into the first hole; but it is too tight and I expect it to break sooner rather than later.

Also, the the base of the strap which attaches the strap to the light is curved on the inside, and the back of Specialized seatpost is flat.

I cannot recommend this light for Specialized road bikes.

I chose this light because it has a hook mount, which I use to attach it to my helmet strap. The hook is very secure, it�s never come loose once in over a year of riding. Even though it�s small and light, it puts out a lot of light. I just bought a 2nd for my commute bike, where it mounts on the rack. I�ve had it on for many hours during long rides, it has never stopped working.

Have NR 1000 light on bike, bought second NR Lumina Micro 900 to mount on helmet for nighttime Fat Biking in Alaska, its nice to see moose before you get stomped. Have been impressed with battery life even at extremely cold temperatures. Blinking feature is nice for extra visibility along roads in the daylight.

This light is so powerful during the day. My initial buy was the Exposure MK3, but I read plenty of reviews on it and decided to pass. My second was the Cygolite hypershot. But read too many mix reviews on the durability of it. I decided to go with niteride because many ppl recommended the brand to me on Reddit for long cycling rides during the day. I needed a rear light that would last 6-9hrs. This thing is extremely powerful and also battery is very efficient depending on what setting you have it.
