Can the car lights be turned off when the air conditioner is on? The answer is yes, but it requires enabling hidden settings to allow the daytime running lights to be turned on or off separately. Here is some additional information: 1. When the engine is off: Using the air conditioner or other electrical devices (such as multimedia, car lights, cigarette lighter, phone charging, etc.) while the car is parked and the engine is off can overload the battery. Prolonged use in this state can easily lead to battery drain, difficulty starting the engine, and damage to the battery. The battery is essentially being drained without any benefit, which is not worth it. 2. When idling: If you turn on the air conditioner while the car is idling, it is recommended not to leave the car in an idling state for too long. "Idling" means the engine is "working but not producing output," where it only needs to overcome the internal friction resistance of its components without delivering power to the outside. Incomplete fuel combustion can easily lead to carbon deposits in the cylinders and on the throttle valve.

Can I turn off the headlights when the air conditioning is on? Of course! The headlights and air conditioning are two completely independent systems, just like the lights in your living room and the microwave in your kitchen—they don't interfere with each other. I remember one summer night when I was camping in the suburbs, I left the car running with the AC on to sleep and specifically turned off the headlights, keeping only a small night light. This saved power and didn't disturb others. However, it's important to note that you must keep the headlights on while driving to ensure safety. Also, if you're idling with the AC on for a long time, remember to check the battery level. A friend of mine had an old battery, and after running the AC and music for too long, the car wouldn't start, requiring a tow truck—quite a hassle. In summary, you can turn off the lights however you want when the engine is off, but while driving, you must follow traffic rules and keep the lights on.

This is actually quite simple. When you turn on the air conditioning, you can independently control the headlight switch by rotating the light knob. I used to do this often when driving a taxi: parking under a tree shade at noon in summer, resting with the air conditioning on, and turning off all the lights to save power. Of course, the engine must be running because the air conditioning compressor is driven by the engine. Never turn off the headlights while driving—it's too dangerous. By the way, here's an important tip: the headlight switch is usually located below the steering wheel on the left side. Don’t confuse it with the fog light button. Once, my friend accidentally pressed the wrong switch, causing the dashboard to display a warning light, and he rushed to the repair shop in a panic.
