The unmanned reef lights of the Florida Keys were navigational aids erected near the Florida Keys between 1921 and 1935. They were intended to mark local hazards and did not need to be visible for as far as the reef lights that were erected near the Keys during the 19th century. By the time the lights in this list were erected, older lighthouses were being automated, and these new lights were designed to be automated from the start. The lights resembled the older reef lights in having a wrought iron skeletal pyramidal structure on a screw-pile foundation. They all originally had lanterns on their peaks, so that they looked like smaller versions of the older reef lights, but had no keeper's quarters.
