Lopolight Series 300-038 - Double Stacked Masthead Light - 5NM - Horizontal Mount - White - Silver Housing

The Lopolight Series 300-038 Double Stacked Masthead Light is the cornerstone of proper vessel lighting and USCG compliance for recreational and commercial boats operating in coastal waters. After years on the water, you know that a reliable masthead light isn't optional—it's essential for safe night operation and meeting federal navigation lighting requirements. This horizontal-mount light is engineered for boats requiring a 5-nautical-mile visible range, making it ideal for center-console fishing boats, cruisers, and commercial vessels where overhead visibility is critical to avoiding collisions and maintaining safe passage after dark.

The double-stacked configuration of the Lopolight Series 300-038 delivers superior light output across a 360-degree horizontal plane while the white LED array ensures long service life and minimal power draw—a game-changer for boats with limited electrical capacity or extended offshore trips. The silver housing resists corrosion in harsh saltwater environments, a practical advantage anyone who has dealt with oxidized brass fixtures will appreciate. At just 3.4 pounds with compact dimensions of 7 x 5 x 9 inches, installation is straightforward on most masthead platforms, and the efficient LED technology generates minimal heat while producing the full 5NM visibility range required by USCG Navigation Rules.

Skippers running offshore or coastal charters, commercial operators, and serious anglers who boat at night will benefit most from this light's reliability and code compliance. Whether you're running home after a late bite on the flats or conducting commercial operations, the Lopolight Series 300-038 delivers the consistent, visible-range lighting needed to keep your vessel legal and your crew safe. The horizontal mount configuration works seamlessly on standard aluminum or fiberglass masts, and the white LED technology pairs effectively with complementary navigation lights to create a complete exterior lighting system that performs season after season in saltwater conditions.
