Dr. LED has introduced its certified 120/240V Six Nautical Mile (6NM) P28S LED replacement bulb for Perko Fixture Figure 1369 and Aqua Signal Series 70 navigation lights.

The 6NM P28S LEDreplacement bulb for Perko, Aqua Signal and other navigation lights from Dr. LED improves reliability for ship operations, the company said. This 6NM P28S Dr. LED bulb is specified for use on the USCG and Navy ships.

In February, Dr. LED announced that its P28S White Polar Star LED bulb (PN:9342004), a P28S LED replacement bulb for the Perko fixture figure 1369 etc. and Aqua Signal series 70 navigation lights, was certified by a USCG-accredited independent laboratory as conforming with the navigation light regulations of USCG COLREG 1972 (International Maritime Organization) and the UL1104:1998 standards.

This high-quality, long lasting P28S LED bulb eliminates having to frequently replace short service life incandescent bulbs.

Developed by Dr. LED at the request of the USCG to improve the reliability of their navigation lights that use P28S bulbs, and to decrease the often hazardous task of having to replace incandescent P28S bulbs while underway, this bulb has also been chosen by the Navy for use in their P28S bulb navigation lights.

It is the only USCG certified aftermarket replacement P28S LED bulb currently available.

Dr. LED is committed to satisfying the lighting needs of the boating public, USCG, and Navy.


The P28S LED bulb can be purchased from Dr. LED’s resellers across the US and Canada or directly thru Dr. LED’s website (www.DoctorLED.com).
