Underwater Focus Lights aren't necessary in all situations but are highly recommended. Digital cameras, both compact and DSLR, focus by detecting contrast at the focusing point. Water absorbs light quickly, so using a focus light allows the camera to see the contrast and quickly focus. Using a focus light is critical for shooting at night (it also serves as a primary dive light), for shooting supermacro and often-times for shooting macro. Many experienced photographers use focus lights while shooting wide-angle into bright sunlight as well.
