Here is what the light looks like. I will have to examine it more closely when I am back at the boat, but I think this is sealed. I would love it to be able to be opened and put in a marine
beam replacement G4 light, but not sure that could happen.
I did find lights that are red/white with 2 wires that fit the holes. They are from quick marine
, i think they are italian, and they the oem manufacturer of the lights on the boat. They have a model with red/white, but it is 2 hot wires. I put one of these in above the nav station, and have that wired for red only.
There is a US subsidiary in MD, which is where I got my lights from.
Also, these guys have lights, but surface mounted and expensive
If you find out if you can open these lights, and put in a red/white replacement, pls let us know. thanks.
