Bike Turning Signal Circuit

his circuit Can be used to left right tuirn on motor bike or vehicles. We need two different circuit one For left Signal and otner for right signal. Here you see the diagram of left right turning signals:-

Diagram:

WE make this light with the Help of White LEDs and 555 Timer IC. The main component of teh circuit is 555 Timer IC. with the help of this IC we Set the time of LEDs.the circuit Diagram of teh circuit:-

Left Signal Diagram

This is the circuit diagram of the left motor turning Signal.  in this Diagram we use two 47 K resistor with 555 Timer IC becasue to set time delay. and use Diode(1N4148)  with the output of the 555 Timer IC. because to remain the current constant. USe 330R in a series with LEDs.
Components: 

1. 47K Resistor(3)
2. 100uF Capacitor(2)
3. 555 Timer IC.
4. Diode 1N4148(2)
5. Npn Transistor 547(5)
6. 10 LEDs(white).
7. 12V Battery(1)
8. Wire.
