Aqua Signal Navigation Lights: LED Replacement Bulb Information

Boatlamps stock a wide range of LED replacement navigation bulbs for your Aqua Signal marine light fixtures. All our LED replacement lamps are manufactured using only high quality, high output, very bright SMD LEDs. To find the correct bulb, please select your existing navigation light series:

Series 20 | Series 25 | Series 40 | Series 41 | Series 42 | Series 50

Please check your actual lamp for correct base type. There are a number of look-alike products on the market that may use a different lamp base. If your navigation light fitting is not shown below, it is important to check which type of bulb is fitted to your fixture before ordering. Often it is quite obvious, however if you have any doubts please email us a photograph of your bulb and its measurements and we should be able to match it to one of our LED lamps.

Aqua Signal Series 50

Aqua Signal Series 50 Navigation Light LED Replacement Bulbs

Popular LED Replacement Lamp: BAY15D (and select appropriate colour for your lamp)

Important: Please do not install LED lamps into light fixtures that leak. A dunking in seawater does them no good and will ultimately lead to lamp failure. Failures due to sea water contamination are not covered by our warranty (or indeed any other supplier’s warranty as far as we know).  

Please note: 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 are 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 our products to retrofit any particular light fitting used for navigation purposes.
