A Faulty Battery
When the ignition is turned off, a bad battery may cause the lights to remain on. Modern remote-controlled cars rely heavily on the voltage of their batteries.
Using both high and low voltages, the car’s digital components communicate with each other. If the battery is faulty, the Morse code in the digital control may start sending out weird signals. As a result, you can do a crank test to verify that the voltage is between 12.65 and 12.70 volts to rule out a bad battery.
Loose and Dirty Battery Cables
A malfunctioning battery cable could cause a vehicle’s dashboard lighting and other lights to flicker even when the ignition is turned off.

Battery acid can seep from the terminal posts if the terminals deteriorate. As a result, cables should be inspected to avoid electric problems.
Problem with the Ignition Switch
The ignition system determines whether the lights remain on or are turned off. It’s possible that a worn-out ignition can cause unforeseen internal damage, resulting in a short circuit in the lighting system.
Low Engine Oil Pressure
When the engine’s oil is low, the oil warning lights will come on. An engine oil loss could affect the car’s electrical system, resulting in dashboard lights that remain even after the vehicle is turned off. The engine should therefore be checked and ensured that it is in the proper working order.
The anti-lock braking system
The anti-lock system malfunctions cause problems with the anti-lock brake system (ABS). ABS functions may be disabled if the braking system malfunctions, which would have an effect on the dashboard’s controls.
Is This Problem Temporary?
It’s better to master basic DIY skills in order to fix dashboard light troubles, even if the problem is transient. If the problem persists after turning off the engine, try restarting the vehicle.
After restarting the engine, the dashboard lights will go off if the problem is a transient one. Disconnecting and reconnecting the car’s battery is an option if the dashboard lights do not adjust themselves.

To get the most out of these lights, it’s best to know what they do and why they’re important.
Can It Resolve By Itself?
You may start driving in the hope that the lights would adjust themselves, which may be true for some vehicles. Engine or battery problems will not repair themselves, therefore the dashboard lights will not go out on their own.
