Waterproof spare bulb 12 V 50 W Ø110 mm, splined halogen

This waterproof replacement bulb is a 12 V, 50 W halogen variant for marine lighting. The nominal diameter is Ø110 mm, corresponding to the specified size designation of 4 inches.

The bulb is intended as a spare part for a wide range of navigation lights and spreader lights. The waterproof design makes it suitable for documented marine fixtures where the bulb is exposed to moisture and weather.

The variant is designed as splined. This designation describes the documented variant design but does not indicate a standardized socket or terminal type.

The bulb is documented as compatible with the fixed 12 V spreader light with item no. 13.243.90, the articulated 12 V spreader light with item no. 13.243.92, and the recessed 12 V hull/docking lights with item no. 13.258.12. The latter fixture uses waterproof 4-inch Sealed Beam bulbs.

Always check the fixture's voltage, wattage, size, and original item number before purchasing.
