[MENTION=210511]Bike Gremlin[/MENTION], I wasn't suggesting OP buy a dynamo hub, I was just trying to figure out what that mount was designed for. A dynamo light doesn't make sense either because the mount is in the middle of the rack rather than to one side. I checked the Specialized website and they don't have any headlights to go there, so I give up.
