You don’t need to swap out the switches if they still click well. Mine were 20 years old. For the bulbs just take the number from the label inside the fixture and look at west marine. They have compatibility tables. It’s very easy. The base of the bulbs are identical if they are incandescent or led, the tops are what is different.look like your bulbs are #912. Look at west marine and they have bulbs that match that number.
see below from west marine website. Btw, you got lucky finding such a new fixture. They are excellent designs.
