Light Structures
Maneuvering a boat at night can be dangerous
and confusing. To aid boaters with navigation and
to warn of hazards, the USCG and the state and
local authorities maintain a variety of light
structures. Some light structures may be equipped
with radio beacons, radar reflectors, and/or
signals.

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.
Range Lights
Range lights are usually visible in one direction
and help a boat operator navigate in a generally
safe direction. 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.
