The beacons consist of two lights that are separated in distance and elevation, so that when they are aligned, with one above the other, they provide a bearing.

Two-phase power can be derived from a three-phase source using two transformers in a Scott connection: One transformer primary is connected across two phases of the supply. The second transformer is connected to a center-tap of the first transformer, and is wound for 86.6% of the phase-to-phase voltage on the three-phase system.

An example of a sector light is the light of the Fisgard Lighthouse in British Columbia. The lighthouse was built to guide ships through the entrance of Esquimalt harbour. The white sector is an isophase light of 2s from 322° to 195°. If the ship sees this white light, it can pass safely. The rest shows a red light from 195 to 322°.
