This toy car is powered by a 9V battery which is connected to a DC electric motor. 3mm led lamp has a 25 mA forward current and 2.1 V forward voltage. After calculations with these values of led, I added a 1/2W (390 ohms) resistor to the circuit. Also, there is a switch in the design. I am not a fan of electric circuits. I hope it will work without an error :)
