Light sensor

Light sensors are gameplay mechanics in Pikmin Forever. They detect certain frequencies of light and activate moving devices if it senses enough light. Normally a module such as the one pictured is embedded in a wall near machinery, and getting enough Mushroom Pikmin near it will activate it. Light sensors can require from 10-30 Mushroom Pikmin, and it does not accept light from the leaders' beacons. Light sensors only appear underground, since Mushroom Pikmin caps only glow underground.
