What is the primary use of dive lights?

The primary use of dive lights is to enhance visibility in low-light conditions and inside wrecks or caves. Divers often encounter situations where natural light is insufficient, such as at greater depths or in environments like caves and wrecks where daylight cannot reach. In these cases, dive lights provide the necessary illumination for divers to see their surroundings, read gauges, and navigate safely.

Using dive lights effectively allows divers to explore areas that may otherwise be inaccessible or dangerous due to poor visibility. Additionally, they can help in spotting marine life and observing details of the underwater environment that may not be visible in dim conditions. Hence, the role of dive lights is crucial for safety and enjoyment during dives in low-light scenarios.
