The U.S. Coast Guard is concerned about the sale and availability of unapproved recreational and commercial vessel navigation lights. Purchasers of such lighting should be aware replacement lighting may be improper for its application due to the failure by manufacturers to meet technical certification requirements. Furthermore, technical advances in marine lighting, such as the use of Light Emitting Diodes (LEDs), rope lighting, underwater lighting, and other various types of decorative lighting, may violate navigation light provisions of the Nautical Rules of the Road.
The attached Marine Safety Alert has been posted by the Coast Guard. Please share to insure widest dissemination. Should you have any questions, contact information for CG-NAV is found within the alert.
