Lights provide temporary illumination in situations where other lighting is not available or is impractical for use, such as during emergencies. Having a pair of these is useful for emergency situations, navigation at night, maintenance, and security patrols during the evening.
Compared to flashlights, lanterns and spotlights shine light over a wider area or a farther distance. These lights are lightweight and have a handle to give you a secure grip when you're on the go. First responders, search and rescue teams, outdoor workers, and enthusiasts use lanterns all the time.
