Overview

The Hella Marine 002984525 is an all-round red navigation lamp with a 360 degree light arc, a black housing that is non-magnetic, and a 2 nautical mile visibility rating. It uses a replaceable 12V / 25W BAY15d incandescent bulb and carries an IP55 rating for rain and spray.

This style of 2 NM all-round lamp is commonly specified on vessels under 20 m when installed in the correct location and height. The housing and lens are made from plastic that stands up to sun exposure and onboard knocks, and the lamp body is built for saltwater use.

Key features

• All-round red light (360 degree) with a 2 nautical mile visibility rating
• Black housing that is non-magnetic and suited to saltwater exposure
• IP55-rated enclosure for wet weather and deck spray
• Horizontal surface mount with cable entry through the base plate and a rubber grommet
• Bayonet-lock style housing for quick access, supplied with a 12V / 25W BAY15d bulb
• Vertically hanging bulb layout with contacts positioned high in the lamp to help reduce corrosion at the terminals
• Meets IMO Col Reg 72 and USCG requirements, with ABYC A-16, BSH, and Maritime NZ approvals listed

Installation and setup

Mount the base on a flat horizontal surface where the lamp can show a full 360 degree arc without being shadowed by antennas, canvas, radar arches, or rigging. If it is being hoisted up a mast, make sure it stays upright so the lens and bulb orientation remain correct.

The cable routes through the base, so plan the run before fastening the unit down. Leave a drip loop, support the wire so vibration does not work it loose, and seal around fasteners and the cable pass-through as you would for any deck-mounted electrical fitting.

Electrical and bulb notes

This is an incandescent navigation lamp that runs with a BAY15d bulb. The included lamp is 12V / 25W; on a 24V boat, the same fixture can be used by fitting a compatible 24V BAY15d bulb rather than feeding 24V to a 12V lamp.

Protect the circuit with an appropriately sized fuse or breaker for the wiring and load, and keep connections dry and well-supported behind the mounting surface.

Use cases on board

This lamp suits sailboats and powerboats that need an all-round red signal in a location like a mast, hardtop, or cabin roof, and want a serviceable bulb-type light in a black housing that does not stand out against dark rigging or hardware.

Maintenance and care

Rinse salt off the lens and housing during routine washdowns so light output stays consistent. When changing bulbs, check that the bayonet-lock housing seats cleanly and that the cable grommet remains snug to keep spray out of the wiring cavity.
