Abstract: A new and improved hazard signal, turn signal, and brake signal system for an automotive vehicle which is characterized in that each of the foregoing signal indications may be provided independently and/or simultaneously without interfering with one another. In a preferred embodiment the system comprises eight two-filament light sources arranged in groups of two sources at each of the four normal corners of the vehicle. One of the light sources in each of the four units serve as either a hazard light or a turn signal light, depending on the desired mode of operation. An important feature resides in that simultaneous energization of the hazard signals, turn signals, and/or brake signals do not serve to override one another, but may be provided simultaneously as separate indications.
