Searchlights are powerful lights used to illuminate large areas or to signal over long distances. They consist of a strong light source, often a high-intensity bulb, and a reflective surface that directs the light into a narrow beam. Searchlights are commonly used in various applications, including military operations, maritime navigation, and outdoor events. These devices can rotate or tilt, allowing them to cover a wide area or focus on specific targets. Searchlights are often mounted on vehicles, buildings, or tripods, making them versatile tools for enhancing visibility in dark conditions or during emergencies.
