For diving at night, a common phrase with respect to dive lights is "Two is one and one is none".
For night dives, a scuba diver should carry three dive lights.
A primary dive light which is usually the larger and more powerful of the dive lights, enough to maintain the lighting required for the whole dive. It's switched on at start of the dive and will only switched off again when emerging from the water.
A backup light (also called the secondary light) which is small and portable, and is carried at an easily accessible location. The main purpose is to provide a backup light source in case the primary dive light fails. As such it ensures safety. The backup light might also be used during day time to enlighten dark places like holes in the reef or signal you buddy.
An indicator light, usually small in size, which can be attached to either your BCD or the head of the air cylinder. It's function is to indicate the position of the diver.
