Does the company offer replacement brackets? I don’t want to buy a whole second light to get a bracket.

On the Q & A section on the product page, BikeSpark says they don't sell extra brackets, and don't recommend moving the light from bike to bike, but they don't say why. It would seem if you can safely remove the light to prevent theft, moving it to another bike shouldn't be a problem. I wanted a second bracket as well and found it wasn't available. I think the 'problem' is that they want to put the bottom-line ahead of customer satisfaction. It's a great light, don't get me wrong, but customers should be able to use it as they see fit.

Does light go out when fully charged?

Yes the light goes out after fully charged

where is the photo of the mounting bracket to the rack ?

The mounting bracket has 2 bolts that fit the standard reflector mounting holes in the rear rack.

Does it come with a mount?

Yes. It's designed to mount on a flat surface like the rear of a metal bike luggage rack which usually has the standard holes pre drilled. The mount stays on the bike and the actual light securely snaps into it. It is the best light you can possibly buy for a bike. Make sure you get the rechargeable model.
