Flasher With Beeper

Here is the simple but interesting project flasher with beeper, can be used in automobile and other application. It can be used as flasher beeper in scooter, motorcycle etc where there is no facilities of beeper with flasher.

Working of the circuit of flasher with flasher with beeper

The heart of the circuit flasher with beeper is IC1 (LM 555) which is used as 1 kHz astable multivibrator. When the circuit flasher with beeper is connected to the power (from turn indicator switch of scooter), output of 1 kHz frequency is obtained from pin number 3 of IC1 (LM555). This frequency is given to speaker through R3 and C2 and beeper sound is heard.

Using Method of flasher with beeper

The circuit of flasher with beeper can be used only to those vehicles, having the facilities of Turn Indicator Switch. Connection diagram is shown in figure 2. Two signal diodes is connected to left and right side each of switch and connected to point A (for power supply).


Resistors (all ¼-watt, ± 5% Carbon)

R1 = 4.7 KΩ

R2 = 10 KΩ

R3 = 68Ω


C1 = 100 KPF (104 ceramic)

C2 = 10 µF/10V


D1, D2 = 1N4007

IC1  = LM555 Timer IC


Speaker 8 Ω
