What is the purpose of a dive light?

A dive light serves primarily to enhance visibility in low-light conditions. When divers explore underwater environments, such as caves, wrecks, or even during night dives, the natural light decreases significantly. A dive light improves visibility, allowing divers to see their surroundings more clearly, spot marine life, and navigate safely through darker areas.

In situations where depth might hinder natural light penetration, such as diving deeper or in murky waters, a dive light becomes essential for safe and enjoyable exploration. It also aids in reading gauges and equipment, providing better clarity to the diver about their surroundings.

While signaling distress or measuring depth might seem relevant, those functions are not the primary purpose of a dive light. Similarly, determining water temperature does not relate to the main functionality of a dive light, which focuses on visibility.
