How to Turn Off Car Lights?

Car light turning-off method: Most car models are equipped with automatic headlights, which can turn off automatically without manual operation. After the automatic headlights are activated, they will automatically adjust the lighting based on the brightness of the surrounding environment. If there is sufficient sunlight or the owner turns off the vehicle, the automatic headlights will turn off. The principle of car automatic headlights is that components such as light-sensitive resistors act as sensors, sending signals to the electronic control unit to determine whether to turn on or off the headlights and switch between high and low beams. The electronic control unit then controls the changes of the headlights and beam settings. Therefore, while driving, if the environment suddenly becomes dark, the headlights will automatically turn on, and if the light is sufficient, they will automatically turn off.
I also used to always forget to turn off the lights when driving my dad's old Toyota. The headlight switch is usually on the left side of the steering wheel, with a knob marked with a light symbol. Just turn it to the far left 'OFF' position. I remember one time I parked without turning off the lights, and the next day the battery was completely dead, so I had to call for roadside assistance. Newer cars are smarter now, like my Corolla with automatic headlights—they delay turning off after parking and shutting down the engine. However, if you manually turn on the fog lights or parking lights, a green indicator on the dashboard will remind you, and you’ll need to turn them off separately. For car modification enthusiasts, note that aftermarket daytime running lights may require an additional controller to sync with the engine start-stop function.
Last week, while teaching my cousin how to drive, I noticed that beginners often get confused with light controls. To turn off the lights, check three spots: rotate the knob on top of the left rear steering column stalk to position 0; there might be a separate fog light button on the center console that needs to be pressed again; and near the electronic handbrake, there’s a wheel for adjusting dashboard brightness. Electric cars are even more unique—when I test-drove a Tesla, turning off the lights required swiping through the 15-inch touchscreen control menu, or waiting for the lights to automatically sleep when the car locks after exiting. A special reminder: if you forget to turn off the parking lights, the battery will likely drain within two days—I’ve personally experienced replacing a battery because of this.
Based on my experience driving over 20 different vehicles, light switch operations can be categorized into four types: traditional cars use a direct twist of the lighting stalk knob; high-end vehicles feature an independent lighting panel on the left side of the steering wheel; most new energy vehicles integrate it into the secondary menu of the central control screen; the most troublesome are old-style off-road vehicles, which have independent switches hidden under the dashboard. Modern models with walk-away auto-lock feature are very convenient, as the lights automatically turn off when you walk 30 meters away. For owners who have retrofitted xenon lights, remember to check the wiring harness controller. Once, a friend's car had its daytime running lights stay on after the engine was turned off, and it turned out to be due to the controller being connected to the constant power port incorrectly.
