We swapped out the tricolour and the anchor
light with LED a few years for about $140US.
The steaming lights are still incandescent.
With the exception of two fluoros in lockers we retrofitted LEDs into all other fixtures and added some additional lights. These were purchased through a seller on eBay for $250 something US.
All in all it was well worth the time and money
. The entire boat, refrigerator
and all run on two 120W solar panels
....with only occasional deficits that require alternative inputs.
