Beacon lights on slide-rafts are water activated and will work for at least 24 hours.

• A. False
• B. True
• C. Only when submerged
• D. They are not water activated

Answer: (B)

Beacon lights on slide-rafts are water activated and will work for at least 24 hours. They automatically ignite when they come into contact with water, providing a steady signal to help rescuers locate the raft after a ditching. This 24-hour minimum duration ensures a reliable light source through the critical first day, independent of aircraft power or other systems. The activation isn’t limited to being fully submerged; water contact is enough to start the light and keep it operating for the required period. If the lights weren’t water-activated or if they required a longer submersion, the statement wouldn’t be true, but in fact they are designed to activate with water and sustain illumination for at least a day.
