Rule 1: The Monumental Fresnel Lens: The 1st-Order bivalve lens weighs five tons and rotates on a frictionless annular pool of liquid mercury. Ensure the mechanical clockwork drop-weights are periodically wound with the cast-iron winch. If the weights reach the bottom, the beam halts!
Rule 2: Pressurized Vapor Mantle: Maintain 35+ PSI in the kerosene fuel cylinder. If the mantle burns low, pump air pressure and ensure the flame burns with blinding white incandescent brilliance.
Rule 3: Salt Spray Cleanliness: Maine nor'easters whip violent sea-spray over the gallery railing. Crusty salt will occlude the lantern panes. Polish the panes frequently to maintain a 15-20 nautical mile warning radius.
Rule 4: Steam Foghorn in Heavy Mists: When the Maine pea-soup fog rolls in, light the compressor shed boiler and sound the deep two-tone horn to steer schooners clear of the Devil's Tooth Reef.
