24V flasher circuit


Posted on Feb 5, 2014

The circuit shown here works from 24V DC and can flash two 24V bulbs alternatively. The circuit is nothing but an astable multivibrator operating at 1Hz and 50% duty cycle. The lamp to be flashed is connected in place of the collector resistor (Rc) of a typical design. 2N3055 transistors which are well known for their ruggedness are used here. The

y can handle collector currents up to 10A. So a wide range of lamps (in terms of wattage) can be connected to this circuit.
