Cygolite makes a hotshot rack mount bracket.
When I say the Hotshot isn't my favorite, keep in mind that it's still a pretty good light, at one point it was probably the best < $50 taillight. It's just that IMO right now you can do better for the same money. That doesn't mean it won't serve you well.
I kind of like having multiple kinds of lights mounted at once.
Like I said above, I think multiple lights can mount in the same mount. I have a Radbot and a Cateye taillight in a Planet Bike mounts right now. The Cygolite mount doesn't look like it's any different from the Planetbike
