great Fast

very fast and correct thank you

I was surprised and disappointed that the bracket did not come with the light holders and thus required additional spending. The purpose of my purchase was so that I can move the lights between my two bikes. As it is winter here in the upper Midwest, I have not had an opportunity to test the bracket out yet.

Can hold firefly securely.

The mount can hold the firefly securely.

Mounts are good but easily stolen

The universal easy attachment mount style works well, but it would be great if there was a way to attach these to handlebars without the silicone strap. I have people steal just the mounts of my bike even though I had the lights with me.
