Yes. Two good solid brackets for two great lights.

The Cat Eye front bracket will definitely fit around oversize bars. It has a good secure clip and can be shortened at a later date if too long, which it probably will be. It wraps around the bar and feeds through a strong plastic thumb screw. A tip is to put a drop of oil onto the screw because mine seized up after a while, when I tried to switch it to another bike.

With great difficulty. You would have to make a bracket to suit. Probably better to buy a head lamp.
