This circuit is designed for a LED light reflector as been posted here. It is designed only for LED and using this circuit for the ordinary bulb will burn the circuit. The operating voltage for this circuit is max 16VDC and the output (LED input) voltage range is 12~14VDC, so please connect it to a serial-parallel LED(input 12VDC) or else it will burn the LED.
This circuit function is to make the LED illuminate while the red rear lamp in switched on and when the brake pedal is pressed, it will activate the RELAY1 and the LED will start blinking. The LED will immediately stop blinking when the brake pedal is released.
Using 555 timer IC as a LED blinker, R1 & R2 can be changed the value to adjust the LED blinking speed to suits your preference. You could also replace the R1 and R2 with preset or variable resistor (value: 100K ohm) for easier speed adjustment.
It is a simple, cheap and easy to make circuit. The cost estimation is around RM10 and can complete within 1 hour.
I hope you'll enjoy this simple DIY
Вкратце- эта схемка для доп. сигнала "стоп". При нажатии педали доп.сигнал начинает мигать.
