Lights and bilge pumps are wired to the boat's switch panel like everything else, but each has its own rules: navigation lights have to shine through set angles, and a bilge pump has to work automatically and pick up the water without running the battery flat.

Navigation lights
Open ›Navigation lights must shine through set angles so other boats can tell your heading. I cover those angles, then mount the side lights and wire them with an all-round white light to the switchboard.
Installing LED docking lights
Open ›LED light bars work as docking lights, but their car-style wiring loom isn't suited to an open boat. I build a waterproof relay circuit, mount the bar on the grab rail and seal the cable entry.
Making underwater lights
Open ›These waterproof 12 volt lights are made from PVC plumbing pipe, mainly for prawning. I cast a halogen globe in resin, seal the lens with O-rings and test them in the water.
Wiring a bilge pump
Open ›Fitting a new bilge pump that runs automatically or by hand from the dash. I wire it with a 10 amp fuse, a field sensor switch and a three- position on, auto and manual switch panel.
