Sea-Dog Stainless Steel Dome Light - 5" Lens

The Sea-Dog Stainless Steel Dome Light with 5-inch lens is a marine-grade accent and utility fixture designed for cabin interiors, helm stations, and galley areas aboard recreational and commercial vessels. Built from corrosion-resistant 304 stainless steel, this dome light withstands saltwater spray, humidity, and coastal environments where standard marine lighting corrodes or fails prematurely. At 12VDC with an 18.4-watt bayonet bulb configuration, it delivers reliable illumination for docked or underway operation.

The fixture comes prewired with an integral on/off toggle switch and a double-contact BA15D bayonet socket, eliminating the need for separate switching harnesses. The 5-inch polycarbonate lens diffuses light evenly across confined spaces without hot spots or glare—critical for night vision preservation when operating in low-light conditions. Surface mounting requires three right-hand fasteners (not included), allowing quick installation on cabin ceilings, bulkheads, or overhead compartments. For LED conversion, the socket accepts a bayonet-to-G4 adapter (Sea-Dog part 442042-1, sold separately), enabling retrofit to energy-efficient LEDs and reducing DC system load on extended cruises.

This dome light suits weekend fishermen outfitting modest cabin cruisers, offshore anglers upgrading aging fixtures, and boaters maintaining fleet vessels where standardized, long-lasting hardware is essential. The 304 stainless steel construction eliminates rust staining on cabin walls and guarantees a lifespan measured in decades rather than seasons—a key consideration in saltwater environments where replacement and maintenance costs accumulate rapidly. The compact profile and clean aesthetic integrate seamlessly into modern and classic galley or cabin designs without demanding renovation.
