Flashing lights and lamps are more common than normal lights. Whether it is a wedding party or a birthday, flashing lights have been utilized everywhere. The reason is that flashing circuits like lamps or lights are more apparent and noticeable as compared to simple lights. Therefore, lamp flasher circuit is everywhere in ambulances, police mobiles, advertising boards., etc. So, if you want to make your flasher lamp. Then, you are in the right place.
The simple lamp flasher circuit needs transistors and some simple components like resistors and capacitors. The supply of 12 volts is also used to power the circuit. The lamp of 10 Watts is used as a load. Cautious, to use capacitors that must be rated 12 volts. Use a good-quality board to assemble the circuit

Circuit Diagram
Working Explanation
This circuit is an astable multivibrator that idea the transistors BC557 and BC139 for this purpose. When the switch is pressed, the transistor works as the multivibrator. The timing of oscillations determines by the capacitor in the circuit. And, The lamp starts flashing
Application and Uses
- It can be used as a Flashing beacon
- It can also be utilized in Automobiles
- Police mobile siren circuit can be cascaded with this
- Ambulances lamp flashers need this
- flashing lights unit has this circuit
- The flashing lights are used for parties and wedding purposes
- Also, For the lightning of billboards and advertising purpose
