 How to make a police strobe light flasher with BC547 transistor

Hello friends. In this video I made the police flashing light circuit. I used the BC547 transistor when making the circuit. You can make this circuit very simply with a 470uF 10V capacitor, a 10K resistor, 5 blue LEDs and 5 red LEDs. Stay tuned for electronic circuit videos. If you like my video, you can subscribe to my channel. I wish you a pleasant viewing.

Put it on the bike, like a shining star at night.


  What's the Strobe light effect?


A strobe is a device giving a fast series of very short intense light flashes. ... The light pulses can have the effect of making action appear intermittent, or of freezing movement altogether, by varying the frequency (speed) of the flashes.


Strobe lights are commonly used for aircraft anti-collision lighting, both for the aircraft itself and for tall stationary objects such as televisions and radio towers

This video shows how to make Strobe light effect using BC547


  You can try changing the value of capacitor. Then you can see the difference result. Use 9v battery or adapter for this circuit. This circuit can be operated using DC 9 – 12v Supply.


  Hardware Component.

The required hardware component of

"LED Strobe light effect with BC547 transistor"

1) Transistor BC547.

2) Red LED 5mm.

3) Resistor 1K.

4) Resistor 15R.

5) Capacitor 470uF.
