ABSTRACT:
A vehicle exterior light flashing unit for use with a vehicle having a pair of rearwardly projecting red and/or yellow lamps such as brake lights or turn signals and one or more white lamps such as backup lights. The unit, which can be connected to such vehicle without interrupting the existing lamp control circuit, energizes the red/yellow lamps alternatingly with the white lamps to produce highly visible alternating sequence of white and red light to indicate a hazardous condition. If the vehicle also includes a third center brake light, it may be energized together with the other red/yellow lamps to produce a pattern of light having an alternating geometric form of a triangle and a horizontal line to additionally enhance recognition.
