Om by 1984 Hunter 34 I have a switch on the DC panel labeled “Deck light”. I have no light out on deck. Anyone know if this was an option and where the wiring from the switch may lead to?

Boat came with a combination steaming and deck light about half way up the mast on the front side of the mast.

The downward looking decklight halogen bulb has a bad habit of burning out or its base corroding and then it won't work.. The steaming light is the forward facing part that should be lit at night (along with regular nav lights) when motoring.
