Overview

The Perko 0946DP1STS is a flush-mount stern navigation light for 12V DC systems on sail or power vessels under 20 meters (65.6 ft.) in length. It is USCG 2 nm certified and uses the included 10 watt bulb, with listed draw of 0.74 amps.

This version has a bezel in polished stainless steel and a black polymer base. The housing measures 3 inches outside diameter, 1 inch deep, and 1-15/16 inches high, so it fits well on transoms and aft bulkheads where space is limited and a round flush light is preferred.

Key features

• Vertical flush-mount stern light for sail or power vessels under 20 meters (65.6 ft.)
• USCG 2 nm certified for the stern-light position
• 12V DC operation with included 10 watt bulb
• Listed current draw of 0.74 amps
• Bezel in polished stainless steel with black polymer base
• 3 inch outside diameter, 1 inch depth, and 1-15/16 inch height
• Uses #8 mounting screws

Compatibility and fit

This part is for boats with a 12V navigation-light circuit that need a dedicated stern light rather than an all-round pole light. It belongs on a vertical surface at the stern, and the compact round footprint helps when replacing an older flush light or working within a tight mounting area.

Installation and setup

Check the available space before ordering, especially the 3 inch outside diameter, 1 inch depth, and screw pattern for #8 fasteners. On installation, the light needs to sit upright on the aft-facing surface so the stern sector remains clear and the light shows correctly at night.

Use on board

This light suits owners replacing a round flush stern light on a small cruiser, runabout, center console, or sailboat that uses a 12V navigation-light circuit. It also fits boats where a stainless trim ring makes sense on an exposed transom or aft bulkhead.
