Daughter bought a new Premium Headlight from Rad Power and she also has the front storage cage. She wanted the new light to be mounted to the center bar in the front. Using 11mm nylock nuts and an 11mm hex head bolt, everything mounted without issue. I used 18mm length bolts, 20-22 would engage the nylock nut. Outter hold is where the bracket for the light is sandwiched inbetween for proper mounting. Enjoy!
