how to put lights on go kart without battery

Adding lights to a go-kart without a battery can be done by using a simple and efficient method using a magneto or alternator. The magneto or alternator generates electricity while the go-kart is in motion, providing power to the lights. Here are the steps to put lights on a go-kart without a battery:

Materials You’ll Need:

  • Go-kart
  • Lights (LEDs are energy-efficient)
  • Wiring and connectors (sufficient length)
  • Magneto or alternator kit (with instructions)
  • Tools (screwdrivers, pliers, wire strippers, electrical tape)
  • Onoff switch (optional but recommended)


  1. Prepare the Lights:
    • Start by selecting the lights you want to install on your go-kart. LED lights are a good choice because they are energy-efficient and draw less power from the magneto or alternator.
  2. Read the MagnetoAlternator Kit Instructions:
    • If you don’t already have a magneto or alternator installed on your go-kart, you’ll need to purchase a kit and follow the manufacturer’s instructions for installation. These kits typically include a stator, rotor, and associated components.
  3. Install the MagnetoAlternator:
    • Follow the instructions provided with the kit to install the magneto or alternator on your go-kart’s engine. This usually involves attaching the stator to the engine and connecting it to the rotor.
  4. Wiring:
    • Route the wiring from the lights to the magneto or alternator. Ensure that the wires are secured and won’t interfere with moving parts of the go-kart.
  5. Connect the Lights:
    • Connect the wires from the lights to the output terminals of the magneto or alternator. Typically, there will be two output wires, one for the headlight and one for the taillight. Connect them accordingly.
  6. Add an OnOff Switch (Optional):
    • To have control over your lights, consider adding an onoff switch to the circuit. Connect one side of the switch to one of the output wires from the magneto or alternator and the other side to the lights.
  7. Secure the Wiring:
    • Use zip ties or clips to secure the wiring along the frame of the go-kart, keeping it tidy and away from moving parts or hot engine components.
  8. Test the Lights:
    • Start your go-kart’s engine and drive it around to generate electricity from the magneto or alternator. The lights should come on when the engine is running and the go-kart is in motion.
  9. Adjust and Secure the Lights:
    • Make any necessary adjustments to the positioning of the lights and ensure they are securely attached to the go-kart.
  10. Safety Check:
    • Double-check all connections and ensure there are no loose wires. Confirm that the lights turn on and off as expected when the engine is started and stopped.
  11. Enjoy Your Illuminated Go-Kart:
    • Once you’ve completed the installation and confirmed that the lights work properly, you can safely use your go-kart with added illumination.

Always prioritize safety when working on electrical components of a go-kart. If you’re not confident in your wiring and electrical skills, consider seeking assistance from someone with experience in electrical installations or consult a professional.
