I also had trouble with the LED cabin lights on my 2010 Farr design B32 Aibrean. Almost all the original LED lights caused problems, typically a few of the LED bulbs start flickering and then a cluster of them extinguished. The lights were LED assemblies in a G4 fitting, not the integrated fitting that Clipper Marine currently supply. I have now replaced the original LED lights with LumiLife G4 units from LED Choice. web site: http://www.ledchoice.co.uk/g4-led-bulbs Current listed price is £6 each, a lot less than those from Clipper Marine. Whether you can use them will depend upon the type of light fitting you have.
They have been in there for only a few months, but have not failed. They are noticeably brighter than the original LED lights and have a wider illumination angle. Hope this helps.
