Different choices to replace the old incandescent cabin lights. You can get halogen, flourescent or LED. Each has its pros & cons.
I decided to get LED lights. I'm embarrassed to say that I bought them 2 years ago and only hooked up one of the four so far.
I was really looking for the red/white fixtures, but couldn't find them. I'm sure there's more styles available now.
I bought them from this place

I'm putting them on teak mounting bases to dress them up a bit.
