Flare is a type of bright, intense light used primarily in emergency situations to signal for help or to indicate a location. It can be a handheld device or a larger aerial signal that burns brightly for a short period. Flares are commonly used in maritime and aviation contexts, as well as by outdoor enthusiasts. In addition to emergency signaling, flares can also be used in various industries for safety purposes. They are often employed in construction sites or during roadwork to alert drivers of potential hazards. Flares come in different colors, with red being the most recognized for emergencies.
