Flashing lamp circuit

A flashing lamp circuit comprising:

• a light source;
• a multivibrator adapted to be connected to a power supply;
• and
• a switch/regulator circuit operatively connected between the multivibrator and the light source, the switch/regulator circuit including:
• a first transistor having a gate, a source, and a drain, the first transistor source connected to the light source;
• a resistor connected between the first transistor drain and ground;
• a diode connected between the first transistor gate and the multivibrator;
• and
• a second transistor having a base, a collector, and an emitter, the second transistor collector connected to the first transistor gate, the second transistor base connected to the first transistor drain, the second transistor emitter connected to ground,
• whereby the first transistor acts as an amplifier switch between the multivibrator and the light source, the first transistor further acts as a constant current regulator between the multivibrator and the light source.
