modern navigation lights

Hi Everyone,
This is my first post so please be gentle with me. i normally make model warships in 1/96th scale you know the sort sirmar, Fleetscale. However i have for a long time wanted to make the graupner sunseeker manhattan 74, well i finally got my hands on one recently and although it is still in the box as i am half way through building a 1/96th scale leander frigate i have been amazed at James  H build thread of his sunseeker. Hope everything is ok there as he has been a bit quiet lately ? anyway can some one give me some ideas about how to make modern navigation lights that work or even where i can buy them, the sort you would find on a modern, well sunseeker, princess ! not the old steaming lights on other boats. LEDS ? Fibre optics ??
i want them obviously to look right and work but its doing my head in how you make them.

Many Thanks folks !
