Pretty darn Cool

  • Familiarity: I've put it through the wringer

Very happy with this light. I do a lot of commuting home from work at dark and some early morning rides. It is simple to mount to your bike. Really simple. and the multiple modes of flash vs steady my be a little overkill, but is cool. Make a game of it and just play around with it. You will be seen from behind with this light

Great Tail Light

    I've had this on my primary commuter for a few years - very durable, great run time on blinking settings, and very visible to drivers. Nice that you can mount the bracket on the bike and still use the light with the attached clip - like running or mounting to the back of the stroller! Side lights are good for extra visibility.

    Does it attach to the bracket on the Blackburn XR-1 Cross Rack?

    Can this light be attached by clipping onto the back of a saddle bag? Or does it need to be attached to the saddle post?


    Yes, it has a non-moving clip in the back, but gravity would be the main thing keeping it in place.

    Don't have my does it come apart to replace the 2 AAA batteries? Three screws are out and it is tight! Help me please, I need this light on. I love it!

    Yes, just pry open. Tight seal keeps grim out.

    Hm. You must have an older model. Mine has an indentation at the bottom for a coin to go in. Insert coin and twist - case pops open.
