Thanks to John for the inspiration (I couldn't find a comment button on your blog to ask permission, so I will just beg forgiveness);
I had planned to do this for some time but it was on the nice to do list. Then one of the ballasts began to give out. I have a spare ballast but the installation was above my pay grade.
John's article is excellent so I won't repeat it here. Suffice to say that I took the "non-soldering" route with components from 1000bulbs.com. My solution was more expensive but any failed components can simply be popped out and replaced. Unit cost of the LED upgrade is approx $30. Labor, as usual, is about $0.01 per hour. Power usage should be approx .3 amps on white and .25amps on red.
I really like the Alpenglow company and I have no doubt that their upgrade would be better quality, but hey, I'm a sailor. I would certainly recommend their new LED fittings as an initial installation.
Alpenglow converted to LED (3000k Warm white and red);
