You can replace then with led bulbs. Just remove one of the old bulbs to verify what style they are.

I replaced every bulb in my boat with LED. Made it much brighter down there and reduced the amp draw considerably. It also reduced the heat associated with some of the halogen bulbs.

Still not really bright below decks, but much better.
