The Battery and Canopy Light for liferafts are essential safety devices designed to provide illumination and ensure visibility during emergencies. The battery is typically a long-lasting power source, designed to work effectively for up to 5 years to power the light and other electronic equipment on the liferaft. The canopy light is used to illuminate the liferaft's canopy, making it visible in low-light conditions or during nighttime rescue operations. The combination of a durable battery and canopy light ensures the safety of the individuals aboard, making it easier for rescuers to spot the liferaft in distress situations.
