Beacon

A beacon is an intentionally conspicuous device designed to attract attention to a specific location.

Beacons can also be combined with semaphoric or other indicators to provide important information, such as the status of an airport, by the colour and rotational pattern of its airport beacon, or of pending weather as indicated on a weather beacon mounted at the top of a tall building or similar site. When used in such fashion, beacons can be considered a form of optical telegraphy.

For navigation

Beacons help guide navigators to their destinations. Types of navigational beacons include radar reflectors, radio beacons, sonic and visual signals. Visual beacons range from small, single-pile structures to large lighthouses or light stations and can be located on land or on water. Lighted beacons are called lights; unlighted beacons are called daybeacons.

For defensive communications

Classically, beacons were fires lit at well-known locations on hills or high places, used either as lighthouses for navigation at sea, or for signalling over land that enemy troops were approaching, in order to alert defenses. As signals, beacons are an ancient form of optical telegraphy, and were part of a relay league.

Teen Wolf

Teen Wolf is a 1985 American fantasy comedy film directed by Rod Daniel and written by Jeph Loeb and Matthew Weisman. The film stars Michael J. Fox as a high school student who discovers that his family has an unusual pedigree when he finds himself transforming into a werewolf.

Plot

Seventeen-year-old high school student Scott Howard (Michael J. Fox) is sick of being average and wishes he were special. His father, Harold (James Hampton), runs a local hardware store. Scott plays basketball for his high school's team, the Beavers, with a not-so-good win-loss record. The girl of his dreams, Pamela Wells (Lorie Griffin), is dating Mick McAllister (Mark Arnold), a jerk from an opposing high school team, the Dragons. After another of the team's losses, Scott begins to notice strange changes to his body. While at a party, Scott keeps undergoing changes and eventually he returns home, locks himself in the bathroom, and undergoes a complete change and becomes a werewolf, while his father demands that he open the door. He tries to refuse, only to finally give in and find his father has also transformed. Harold never told his son about the condition because "sometimes it skips a generation" and he was hoping it would not happen to Scott. Needing someone else to share his secret, Scott confides his best friend, Stiles Stilinski (Jerry Levine), who accepts Scott's werewolf status. However, Scott inadvertently reveals his transformation to the public at one of his basketball games. After shortly stunning the crowd with The Wolf, Scott goes on to amaze them with his newfound basketball skills.
