Which component helps prevent light security issues on a ship?

Light traps are designed to minimize light pollution and maintain security protocols on a ship. They work by controlling and redirecting light to prevent unnecessary illumination that could reveal the ship's location or internal activities, which is crucial during sensitive operations or in environments where stealth is important. By employing light traps, a ship can maintain a lower profile, making it more difficult for unauthorized entities to detect it from a distance, thereby enhancing overall security.

In contrast, flashlights provide localized illumination when needed but do not inherently contribute to preventing light security issues. Backup generators are essential for ensuring power supply continuity but do not specifically address the concerns related to light security. Emergency beacons are designed for indicating distress and do not prevent light security issues; instead, they are used to signal for help in emergencies.
