Coast Guard warns vessel operators to use proper navigation lights

摘要

The U.S. Coast Guard has issued a safety alert warning operators that they should not use unapproved navigation lights. Inspected commercial vessels must be outfitted with navigation lights that meet or exceed certification requirements, the Coast Guard said in the November 2015 safety alert. Using lights that don't provide the proper chromaticity, luminous intensity or cut-off angles can potentially lead to accidents. The agency said vessel owners typically buy unapproved lights because they're less expensive.
