Photo Caption:

A DCB-224 beacon was installed in Gay Head Lighthouse in 1952. Basically it is two back-to-back drums with a red filter on one end of the drum and a white filter on the other. The lens then rotates slowly to flash first one light then the other. This is the lens that the Coast Guard wants to remove. (Lighthouse Digest photo by Philip Hunter.)
