Double-Deck Masthead Light – High-Visibility Navigation Lighting

This double-deck masthead light is engineered for vessels that require two vertical white lights to comply with international COLREGS regulations. Designed for commercial ships, workboats, and yachts over 50 meters, it provides an unobstructed 225° arc of visibility with intense brightness for safe nighttime navigation.

Constructed with a corrosion-resistant marine-grade aluminum housing and tempered glass lens, this light delivers reliable performance in the harshest saltwater environments. The dual-lamp configuration ensures redundancy, so even if one lamp fails, your vessel remains visible to other traffic. Equipped with standard 12V/24V operation and a low-draw LED option, it offers energy efficiency without compromising on output.

Whether you are retrofitting an existing vessel or outfitting a new build, this double-deck masthead light meets the stringent requirements of maritime safety standards and simplifies installation with its universal mounting base.
