This waterproof sealed-beam incandescent bulb is a 12 V, 35 W spare bulb for marine searchlights, spreader lights, and compatible deck and stern lights. The bulb has a diameter of Ø110 mm and belongs to the 4-inch size class for sealed-beam light sources.
The integrated sealed-beam construction combines the light source and reflector into a single, waterproof unit. The front lens is ribbed for use as a spreader light, where the glass design shapes the light to suit the intended fixture.
The bulb is documented as a spare bulb for the fixed and articulated 12 V spreader lights with item nos. 13.243.90 and 13.243.92. It also fits the angled deck light 13.256.12, the straight deck light 13.257.12, and the recessed stern light kit 13.259.12.
Compatibility must be verified based on the fixture's spare part number as well as the requirements of 12 V, 35 W, and Ø110 mm. Other bulbs with the same diameter may have a different voltage or wattage and are therefore not necessarily suitable as replacements.
