Perko Vertical Mount Stern Light Stainless Steel

The Perko Vertical Mount Stern Light in Stainless Steel (MPN 0939DP1STS) is a marine navigation fixture engineered for demanding saltwater environments. Built with a stainless steel top and black plastic base, this stern light delivers corrosion-resistant performance in conditions where standard finishes fail. Designed as a flush-mount installation, it integrates seamlessly into existing boat structures without requiring external brackets or hardware extensions.

The vertical-mount configuration positions the light for optimal visibility along the vessel's centerline, meeting Coast Guard requirements for aft-running lights on recreational and commercial craft. Stainless steel construction resists oxidation and salt spray degradation that compromises standard brass fixtures over extended coastal operation. The compact 7-inch height and 4-inch width fit standard mounting footprints, while the flush-design installation minimizes wind load and deck obstruction—critical considerations for vessels operating in rough seas where raised hardware creates snagging hazards or structural stress points.

Perko stern lights serve offshore fishing operations, coastal patrol duties, and long-distance cruising where navigation lighting must function reliably through salt spray, UV exposure, and thermal cycling. The black plastic base provides electrical isolation and reduces galvanic corrosion when mounted to aluminum or composite hulls. At 0.35 lbs, the fixture adds minimal topside weight—a consideration for performance boats where every pound affects fuel efficiency and handling.

Perko has established itself as a marine hardware manufacturer serving military, commercial, and recreational sectors for over a century. This stern light represents the brand's commitment to stainless steel marine fixtures that withstand continuous saltwater exposure without the maintenance or replacement cycles associated with brass alternatives.
