Why doesn't the electric vehicle light up after inserting the key?

[McCassidy]

Here are some reasons why the electric vehicle lights may not turn on: Relay failure: If all the lights do not turn on, there is a high probability of a wiring issue or a problem with the relay switch. If only one light does not turn on while the other does, it is most likely a bulb failure or poor contact. Fuse damage: When the headlights fail to turn on, it could also be due to a blown fuse causing an open circuit. Insufficient battery power: Turn the ignition key to the 'on' position; for one-button start models, press the start button twice without stepping on the brake. Turn on the headlights, and if the light noticeably dims or does not turn on at all, and the horn sounds significantly weaker than usual or does not sound at all, it can be judged as insufficient battery power. In such cases, you can seek help from nearby vehicle owners for emergency measures such as jump-starting, borrowing fuel, or towing.
