How to make a powerful flasher using one MOSFET
This flasher circuit has a number of very significant advantages. Firstly, it is simplicity, and secondly, power: the switched current can be up to 50 A, which is clearly not small. Thirdly: the circuit is connected to the llama circuit break and does not require additional power. And these are far from the only advantages of this device.
This flasher can be easily used, say, instead of a turn signal relay on auto-moto equipment.

Flasher circuit
The operation of the flasher is simple. When feeding, the transistor is locked and the lamp does not light. A wave delay circuit is assembled using capacitors and resistors. Through the resistors, the capacitors begin to charge one by one. As soon as the voltage of the latter is sufficient to open the transistor, the transistor will open. After this, through the resistors, the capacitors will begin to discharge one by one. Until the transistor closes. The cycle then repeats ad infinitum.
The circuit is operational from 6 V to 25 V.
Do-it-yourself powerful flasher on one transistor
We solder minus capacitors in a row to the drain of the transistor.
Solder a resistor from the source to the capacitor.
Solder the other two resistors.
We connect the minus from the power supply.
We connect the plus through the incandescent foot.
Turn on the source. The paw blinks.
