USE LEDs for low power drain, I'd use separate running and stern lights. Maybe hang an around light for the anchor light from the spreader rather than chase a wire up the mast.
Basic rules:
- Sidelights are red (port) and green (starboard) and shine from dead ahead to 112.5° aft on either side.
- Stern lights are white and shine aft and 67.5° forward on each side. (Thus, the sidelights and stern light create a full circle of light.)
- All-round lights are white and shine through 360°.
- Masthead lights are white and shine from 112.5° on the port side through dead ahead to 112.5° on the starboard side. They must be above the sidelights.
- Sailboats under power are considered powerboats.
- Sidelights may be combined into a single "bicolor" light.
- Powerboats less than 20m (65.7') in length need to show sidelights, a stern light and a masthead light. Power vessels less than 12m may show a single all-round light in lieu of the separate masthead and stern lights.
- Sailing vessels less than 20m in length need to show sidelights and a stern light. These may be combined into a bicolor light and stern light, or a single tricolor light at the top of the mast. Sailing vessels under 7m must have an electric torch or lantern available for collision avoidance.
- Oar-driven vessels can show either the sailboat lights, or use the electric torch/lantern option.
- When anchored outside a special anchorage, power and sail vessels under 20m must display an all-round light. Vessels under 7m are exempt, unless anchored in a narrow channel or anchorage, or where other vessels usually navigate.
- Sailboats with sails up during the day, but which are also under power, must fly a black "steaming cone," with its point downward, where it can be seen. When under power they must follow the rules of the road for powerboats.
Notes
- Boats under power under 40' can substitute a single all-round light for separate stern and masthead lights
- Boats under 65'7" can substitute a single bi-color light for sidelights
- Sail boats under sail under 65'7" can substitute a tri-color light for separate sidelights and stern light.

Sounds good but you’ll still need a “masthead" (steaming) light if running the O/B . http://gosailing.info/navigation-lights-colregs/
Hi All,
I'm kitting out Black Opal to do the Texas 200 and will have evening sails. The boat has no lights but will have a power system, with charger for the battery. Was thinking that a tri-color masthead light (lED) would be the most effective/efficient. Comments/advice appreciated.
