Weems & Plath Q Steaming/Masthead LED Nav Light in Black Housing

Typically, the light is called a Masthead light for power vessels and Steaming light for sailing vessels, but these terms are sometimes used interchangeably. Like those in the LX Collection, this light is made using solid aluminum construction and a cast acrylic lens. The Q Steaming/Masthead LED Nav Light exceeds 5 nautical miles of visibility and is certified for both power and sailing vessels that are up to 164 feet in length. 

New to the Weems & Plath OGM Series, the Q Collection is the next generation of LED Navigation lights and incorporates the latest LED technology using a modular, modern design. All Q Collection lights are upgradeable, more efficient, and 20-30% brighter than LX Collection lights. 

Includes a waterproof, quick-disconnect plug with a 6-foot mating cable assembly featuring a PVC jacket. Mounting bracket sold separately.
