Sounds like a bad ground on the mast
common lead for the deck/steaming light, or two of the three leads interchanged - probably the deck & ground leads.
The steaming light may be using the deck light as a ground return (the higher wattage bulb has lower resistance so doesn't light visibly). When the deck light alone is on, it feeds the other panel light via the steaming bulb filament.
Been there, done that, saw that the rigger missed that brown is hot, blue ground, in Euro wiring
