The Light Bulb Switch is a story object in Bomberman Max 2.
Description[]
They are the switches that are powering-up the Mini-Mini Device. They are 5 in total and are found at the end of each world, each guarded by a respective boss. Once a boss is defeated, Bomberman or Max will automatically turn the switch off in that particular world. The light of the area will then be no more, weakening the device.
