Overview
The Perko 0939DP1STS is a flush-mount stern light for sail or power vessels under 20 meters (65.6 ft.) that run a nominal 12V system. It is rated for 2 nautical miles of visibility, uses an incandescent 10W bulb, and has a polished stainless steel top with a black polymer base.
This model is for replacement use only and suits installations where the light mounts on a vertical surface at the stern. Its body measures 3-3/8 in. high, 5-3/16 in. wide, and 1-1/2 in. deep, which helps when you are matching an existing footprint on a transom or aft bulkhead.
Key features
- Flush-mount stern light for sail and power boats under 20 meters (65.6 ft.)
- 2 nautical mile visibility
- Nominal 12V setup with bulb included
- 10W draw at 0.74 amps
- Polished stainless steel top with black polymer base
- Mounting layout uses #8 screws and a 2-1/8 in. hole for the socket holder
- Built for replacement use only
Installation and fit
This light is meant to mount on a vertical surface that is perpendicular to the boat centerline and faces astern. That makes it a practical replacement for many existing stern lights on transoms and aft bulkheads where a flush installation is already in place.
Before ordering, it is worth checking the cutout and screw pattern against the current installation. The mounting template calls for two screw holes and a 2-1/8 in. hole for the socket holder, so it is easier to confirm fit before drilling or reworking the mounting area.
Electrical and service notes
This is a nominal 12V incandescent light and it is supplied with the correct bulb for that system. Replacement bulb service uses Perko 0070DP0CLR, a 12V 10W bulb.
It is a good match for owners replacing an older stern light on a cruising boat, fishing boat, or sailboat that still uses a conventional 12V navigation-light circuit and needs a stern light sized for the under-20-meter category.
