- Faulty ignition switch: The ignition switch may be worn out or damaged, preventing it from sending a signal to the starter motor unless the lights are turned on.
- Faulty wiring or connections: There may be a problem with the wiring or connections between the ignition switch, the starter motor, or the battery, causing the starter motor not to receive the necessary power to start the engine unless the lights are turned on.
-Malfunctioning starter relay: The starter relay may be faulty, causing it to fail in engaging the starter motor unless the lights are turned on, which provide additional power to the starting circuit.
-Defective battery: If the battery is weak or has poor charge, it may not be able to provide enough power to start the engine on its own, but when the lights are turned on, they draw power from the battery, reducing the load and allowing the engine to start.
Note: It is important to have the vehicle inspected by a qualified mechanic or automotive electrician to accurately identify and resolve the issue.
Attempting repairs without proper diagnostic skills and knowledge can lead to further damage or safety risks.
