ABSTRACT:
A flashing warning light assembly of a type including a voltage source (s), a transformer gate (W), first and second storage condensers (C1 and C2), flash tube (B), an ignition circuit (T, Z), and an electrical switch (T1) in series with the first storage condenser which is controllable electrically. A monitoring circuit (R1, R2, V1) is further included which senses the charge voltage of the first storage condenser and compares it with a reference voltage, opening the electrical switch when the charge voltage exceeds the reference voltage. The apparatus of this invention provides a flashing warning light assembly which is easily and cost-effectively producible and which, while reliably igniting the flash tube, makes possible the influencing of energy or light intensity of produced light flashes.
