In 1953 the United States Coast Guard published an Aids To Navigation manual which contained complete instruction on the operation and maintenance of all aids to navigation equipment currently in general or supplementary use. This manual serves as an excellent treatise for anyone wishing to gain increased understanding on how such critical equipment operated. We have digitized this manual which relate to lighthouses and make the following sections available for reference. Click any of the links below to download that section in Adobe PDF format. Note that these files are rather large, so the size of each file is listed in megabytes to give an idea of download speed with your Internet connection.
