I use two smart lunar R1 and they're bloody bright with fresh batteries.
the smart bracket has two diameter clasps in the box with the lights one for seatposts and another smaller one for things like chainstays. there's also 2 rubber strips to protect/pad out the inside of the clasps.
with the smaller clasp and the thicker piece of rubber wrapped around I was able to fit them to the rear tubes of my tortec rack. they would swivel sideways if pushed or if I leant the bike against something but were solid when riding about.
the lights clip securely onto the bracket too.
and finally the angle at which you mount the light on the bracket is adjustable so you could probably fit it on a chainstay and angle it down so it wasn't point up at a drivers eyes if you wanted, just dont put it where it'll get wet or could get knocked into the wheel.
