Lights and Lighted Structures
Maneuvering a boat at night can be dangerous and confusing. To aid boaters with
navigation and to warn of hazards, the USCG and state and local authorities
maintain a variety of light structures. Some light structures are equipped with radio
beacons, radar reflectors and/or fog signals.
Range Lights
Range lights are usually visible in one direction and help a boat operator navigate
safely. Steering a course to keep range lights arranged in a line (one on top of the
other) will help guide a boat through a channel.

Minor Lights
Minor lights are colored according to the buoyage marking system in use. They
are similar to lighted buoys, except they are usually higher and on more stable
platforms to increase visibility. Most minor lights are part of a series to mark a
channel, river, or harbor and fairways.
