Can the AUTO headlight setting be kept on for a long time?

The headlights can be kept on AUTO mode continuously, with the following details: 1. It's safe to keep the headlights on AUTO mode for extended periods, as AUTO mode does not control high/low beam switching. Automatic headlights only rely on sunlight sensors to determine ambient brightness and cannot analyze real-time changes in surrounding conditions to select between high and low beams. 2. If you want automatic headlights to control high beams, you need to push the combination light switch forward to the high beam position, then turn the knob to AUTO position, which will enable automatic high beam activation. Additional information: 1. When driving, the headlights will automatically turn on when ambient light becomes dim and turn off when it brightens. 2. Automatic headlights have a delay in activation - it takes about ten seconds after the light sensor detects darkness for the headlights to turn on automatically. According to traffic regulations, headlights must be turned on before entering tunnels, so manual activation is still required when approaching tunnels.
A veteran driver with eight years of experience tells you that keeping automatic headlights on long-term is completely fine. This feature is designed to be used continuously—it automatically turns off when the sensor detects sufficient daylight and activates for illumination at night. I haven’t manually adjusted my headlight switch in three years, with zero malfunctions. The real benefit is peace of mind: no distractions when driving through tunnels or at dusk—just focus on the wheel. Modern car electrical systems undergo load testing; as long as voltage remains stable and no reckless modifications are made, prolonged use can actually protect bulbs from impact caused by forgotten switches. Just remember to wipe the light sensor on the windshield after rain to prevent fog from affecting its judgment.
From a young car owner's perspective, automatic headlights are an absolute must-have feature! On the day I picked up my car, the salesperson taught me to set it to AUTO mode, and I haven't touched it since. After six months of use, I've never encountered any issues. The sensors detect when it's getting dark and turn on the lights, reacting much faster than I could in tunnels, significantly enhancing driving safety. I checked the user manual, and the manufacturer clearly states that it can be used long-term, with redundant circuit designs. The only thing to note is not to spray high-pressure water directly at the sensor area when washing the car, but otherwise, there's no need to worry in daily use. I keep mine on throughout my commute, and when I see drivers next to me manually turning on their lights at traffic lights, it just feels outdated.
