These Bi-Color Polar Star 41 bulbs are specially designed as direct LED replacement bulbs in Aqua Signal Series 41 navigation lights (in which the bulb socket is at the top of the fixtuire, and the bulb hangs down).
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 (approx 1W) makes them the perfect way to reduce energy consumption.
These are BAY-15d bulbs - BA (bayonet base), Y (indexed pins), 15mm diameter base, d (double contact)
They can be used in bi-colored Aqua Signal series 40, 41, & 50 navigation fixtures.
