Super bright light emission BAY15D bayonet replacement LED navigation bulbs which fit most navigation lights manufactured by Hella Marine, Aqua Signal, Perko and other manufacturers.

Our high output 5050, 266 Lumen lamp (CW) is suitable for use in most white navigation light fittings that use traditional incandescent bulbs and is ideal for both 12 Volt and 24 Volt systems. They have a mast top visibility of +1.5 nautical miles.

In cool white this LED lamp can be used for stern, steaming and mast head anchor light elements of tri colour lights for all boats up to 20 metres. Do not use cool white lamps behind separate red or green lens or combined bi colour lights as the output colours will not be correct for navigation purposes.

In warm white it is suitable to use behind the bi-colour red and green combined lenses for boats up to 12 metres (39ft). For boats up to 20 metres see our Bi & Tri Colour products. 

For the brightest coloured light output we recommend using our 24 SMD 2835 BAY15D green lamps behind separate green lenses and 24 SMD 2835 BAY15D red lamps behind separate red lenses. These coloured lamps can be selected from the drop down box above.

For larger vessels and for owners who wish to be seen over much greater distance see our very high output lamps.

All of our lamps have our on-board PWM Buck-Boost electronic control circuit which combine with our high output SMD LEDs to give consistent light output and a very long service life. The lamps are also protected from damage by voltage transients (spikes) and have a built in electronic fuse that shuts down the individual lamp should it develop an internal fault. These lamps are designed to minimise EMI, unlike other similar looking lamps sold for non marine use. We utilise specially designed PCB layouts which avoid tracks acting as antenna that radiate EMI (electromagnetic interference).

Boatlamps recommend using Contralube 770 on all lamp holder contacts and other connections on your boat. This product will protect against contact corrosion which is the most common reason both LED and traditional incandescent lamps flicker or fail.

Please regularly check that your navigation light fixtures are water tight. Gaskets harden over time and poorly sealed cable entries are prone to leaking. This is very important for bow mounted fixture that can be submerged occasionally in heavy seas. Our warranty specifically excludes damage to LED lamps due to salt water contamination. We can supply waterproof lamps for use in exposed light fixtures such as deck level port, starboard and bi-colour lights.

These lamps are not polarity conscious as they are fitted with a diode bridge rectifier and can therefore be connected either way without damage.

 Our LED lamp replaces this bulb type

Try to mount AIS and other sensitive antenna remote from all LED lamps, as far is practicable. Some sensitive receivers can be affected by the low level of EMI emitted from LED lamps.

Important: In common with other replacement LED lamps on the market, it is not possible to have any sort of marine authority certification for individual replacement bulbs. These LED lamps are easily visible at distances exceeding 3nm in standard fixtures and is one of the brightest replacement LED bulbs available. Given the vast array of navigation light fittings installed on marine vessels, it is the user’s decision alone whether to use this product to retrofit any particular light fitting used for navigation purposes.
