Well welcome to the SBO forum
@CGCaptain . The Ranger 23 is a nice boat. You doing this project with the mast down on the hard or considering the opportunity to adventure, climbing the mast and plugging in lights while swinging in the air.
I can attest, pulling the mast and standing on the ground is a better plan.
Now for the secret about lights on sailboats. The manufacture bought one from a supplier, possibly Perko, and any previous owner may have changed it with a light from a different supplier. When you look at the light you may find that corrosion has altered the appearance and the plastic lens of the light. Here is where your desire to sprinkle baubles on your boat (I call my boat by her female name), and the bank "brake" may not be possible to accomplish. Sailboat owners often refer to this as "Break out a Boat Buck".
But I digress. You will need to identify the light fixture and the type of bulb used. Then you can look online or at a chandler for a matching bulb design i.e. need bayonet, festoon or even G4. (here is an example
Marine Light Bulbs & Replacement LED Bulbs | Fisheries Supply).
Once you know the type of bulb used in your boat fixtures you can look at the SBO Shop and see if there is a match. Always good to reward the SBO shop. they have good prices and they sponsor this forum. Just a thought.
