There are also many aftermarket brackets online.
Bending it is the first thing I thought of...and certainly the simplest. May give that a try if I can't come up with anything else. It would be nice to have the light a bit more underneath the rack if possible, just to avoid any possible conflict with items being carried on the rack.
