These LED lights are no bigger than a pinky finger, but, in combination with the mirror, can be seen up to 28 miles out to sea on a clear night. The mirror is about ten feet tall and was handcrafted in France in the 1930s specifically for the lighthouse. Prior to the installation of the electrical lights (at first, luminescent lights) and the mirror, the light was fueled by gas, and prior to that, lamp oil. The US Coast Guard maintains the lights.
