Glowbulb

A glowbulb was a device which could wink out when overloaded. When he was nearly shot down in battle due to the reprogrammed R2-series astromech droid on Wes Janson's X-wing starfighter, Luke Skywalker felt that he would have winked out like one of these if not for a warning from the Force.
