My 1985 model never had a light as far as I could tell but I think there was a switch for it on the power panel. It could have been an option. I've never missed it because I only used the boat for racing. If I'm not mistaken the mast head light is just used at anchor and is not a nav light. Some cruising sailors will undoubted correct or confirm this. I would think any light you hoist aloft while at anchor would work for that function and perhaps that was the original intent with this design. I also noted that I never had a stern nav light also, which I think is a requirement for night navigation, not sure why I had the bow light but no stern light. There is a hole in the center of the stern where I suppose one could have been mounted, just don't know as it was missing when I bought the boat. Hope you get a better answer from some others.
The four navigation lights on a sailboat include a bow red/green (this could be one or two lights), stern white light, a white steaming light or bow light and an anchor light which is an all around white light mounted on the mast. The bow red/green and stern white light must be visible for two nautical miles and illuminated any time the boat is under way either by sail or by power after dusk and before dawn. The steaming light must be visible for 2 nm and illuminated any time the boat is under power after dusk and before dawn. The anchor light must be visible for 2 nm and illuminated any time the boat is at anchor after dusk and before dawn. The anchor light doesnít have to be permanently mounted on the mast top, but must be raised most of the way up the mast. The trick is that the lights must be visible up to 2 nm from the boat. Many LEDs and informal anchor lights donít meet this requirement. It should be said that all sailboats are subject to these regulations, not just cruisers. Iíve seen some racing boats that donít have proper lights but which sail or motor at and after dusk. This happens quite often during the fall sailing season when sunset is around 6:30 pm. Anyone who violates these regulations is subject to fines in most US states. It can also be a danger to oneself and other boaters. A satisfactory (but not necessarily legal) solution is clip-on red/green and stern lights. Theyíre like a couple of flashlights.For those rare instances that a racer finds themselves out after dusk this is a pretty good backup.
My 1983 had a steaming light mounted on the mast. I replaced it with a model that had a steaming light and a downward pointing deck light. If my poor memory serves me correctly the steaming light also indicates that you are a sailboat thus you should have right of way to powerboats
