Some racks don’t have a license plate mounting point thus not allowing you to mount the light bar. If this is the case an accessory is available to allow you to strap the unit to the bicycles that are mounted on the rear of the vehicle, remembering that the unit MUST be located centrally on the vehicle, as blinkers are fitted to the light bar and the top of which MUST not be more than 1300mm above the ground, (Refer to your local requirements)
