These Polar Star 40 series bulbs are specially designed as direct LED replacement bulbs for many popular brands of bi-color bow lights such as Aqua Signal, Hella, Perko, and Attwood.
They are fabricated from the highest quality components to assure long life and trouble-free functioning.
Patented internal circuitry provides consistent brightness and makes them immune to life-shortening voltage fluctuations.
Incredibly low power draw (~1W) makes them the perfect way to reduce energy consumption.
These are BAY15d bulbs - BA (bayonet base), Y (indexed pins), 15mm diameter base, d (double contact)
The indexed pins ensure that the bulb faces in the correct direction within the light fixture.
They can be used in single colored Aqua Signal series 40 and 41 navigation fixtures.
Bi-color Hella series 2984 and 2386.
Bi-color Perko series 200 (Bulb Fig. 0375).
