12V / 24V Bay15d LED Navigation Bulb – 66 LED Marine Replacement Lamp (Port, Starboard, Mast)

Upgrade your boat’s navigation lighting with this 12V / 24V Bay15d LED navigation bulb, designed to replace traditional tungsten marine navigation lamps with a brighter, more efficient, and longer-lasting solution. Featuring 66 high-output LEDs and regulated 10–30V operation, this low voltage marine bulb dramatically reduces power consumption while maintaining reliable visibility for port, starboard and mast lights. Ideal for yachts, canal boats, sailing vessels and motor cruisers operating on 12V or 24V systems.

This 66 LED navigation lamp has been engineered specifically for marine use, offering a modern alternative to traditional filament bulbs used in navigation fittings.

By consuming just 3.1W, it provides efficient, consistent illumination — helping reduce battery drain during extended night cruising or when running multiple onboard systems.

The warm white version is particularly suited for use behind coloured navigation lenses (such as red port and green starboard filters), as it produces the correct colour output when used with traditional marine fittings.

Colour Options Available

• Warm White (352 lumens) – Best choice for use behind coloured navigation filters (traditional port & starboard lens fittings).
• Red (111 lumens) – Suitable for port lights when used with a clear lens.
• Green (274 lumens) – Suitable for starboard lights when used with a clear lens.
• Cool White (386 lumens) – Ideal for mast lights or white all-round navigation lights.
