Abstract
Abstract The invention relates to a flashing electric lamp comprising a casing closed at the front by a removable glass and at the rear by a standard electric lamp base. A flashing electronic tube is located inside the casing and forms with electric components a relaxation oscillator. The invention has particular utility for signalling by lights, for illuminated decorations and for illuminated panels.
