What powers the two canopy lights on liferafts?

Liferaft canopy lights are kept ready to go with internal batteries that don’t rely on external power sources. Dry cells or water-activated batteries are used because they have a long shelf life and can activate automatically in water, which is ideal after inflation and immersion in the sea. This means the lights will come on when you need them without needing to recharge or crank something, providing reliable illumination in an emergency. Solar panels wouldn’t be dependable inside a canopy or when shade or poor light limits charging; a wind-up dynamo requires manual cranking and may not sustain light for long; USB rechargeable packs need a charging source that isn’t available in survival conditions.
