ATON/Advanced Notice of Change 22457 Location: 32-45.48N 079-50.59W Aid Name: Charleston Light LLNR: 195 Action: CHANGE Action Type Change Light Signals The U.S. Coast Guard has approved the following changes to the Aids to Navigation System in the Charleston Harbor: Charleston Light (LLNR 195) will permanently have the nominal range reduced from 20NM to 17NM due to the installation of an LED optic. This optic will ensure the light is more reliable as parts and essential components become harder to source for the existing optic. Any part or component failure with the current equipment could potentially lead to an extended period where the light would be extinguished. The flash characteristic and color will remain the same.
