I went up the mast at the weekend and removed the steaming light bulb to replace for an LED, but cannot find a similar one on the internet anywhere:

It is 44mm from end to end.
Any idea what type of bulb this is, and where I can get an LED replacement in the UK?
The dimple ended 44mm festoon lamp is used in AquaSignal Series 25 navigation light fixtures manufactured up to mid 2010. AquaSignal changed the lamp to a 44mm cone ended festoon on series 25 after that date.
