Don't take the toy car apart yet. Solder the bulb (or LED) to both ends of the motor
Turn the wheels of the toy car hard (if you let the motor run straight). , the number of revolutions is too low and it may not work. (it will light up, you need to turn the wheel through the reducer to turn the motor quickly), that is, let the motor run.
Check if the bulb has a light long live. If it is LED, you can try forward and reverse rotation.
I wish you success.

Remember that energy can be transferred from one to another. When you power the motor, electricity is converted into kinetic energy (not counting heat), so when you spin the motor with your hand, the energy from your hand; is converted into electrical energy;
You can try using a motor to drive another motor, when a motor after power on, the motor B shaft is driven to rotate and a voltage will be output. on the brush of motor B. I tried it, and it works, but if I want to make a manual generator, the small motor has limited power and the voltage it puts out is relatively low.
