Where is a personal safety light typically attached during a dive?

A personal safety light is typically attached near the tank valve during a dive for several important reasons. This location allows for easy access and visibility, ensuring that the diver can activate the light quickly in low-light conditions or emergencies. Positioning the light near the tank valve keeps it close to the diver's primary equipment, making it less likely to be misplaced or overlooked.

Additionally, having the light near the tank valve helps to ensure that it is easily noticeable to dive buddies or team members, enhancing safety during a dive. When visibility is compromised, a light at this location can be a reliable signaling tool. Being near the tank valve also minimizes the risk of entanglement with other gear since it is stowed away from more mobile parts of the diver's equipment.

The other options, like attaching the light to the buoy, wetsuit, or dive computer, may not provide the same level of safety, visibility, or convenience, which is why near the tank valve stands out as the most logical and effective location.
