Why is the Corolla's automatic light always on?

Corolla's automatic light may stay on continuously if the sensor on the front dashboard is covered. Corolla, once known as Corolla Altis, is a brand under Toyota Motors. It is equipped with Michelin (215/45 R17) tires, TRD Sportivo high-performance shock absorbers, TRD TF4 17-inch sport rims, reinforced clutch, and high-performance brake pads to ensure optimal sports performance. The Corolla features a moderate, elegant, and stable exterior design, with a minimalist interior style, a well-organized dashboard layout, and spacious, comfortable seats.
Last time my Corolla's automatic headlights stayed on during the day, and it took me a while to figure out why. The automatic lighting system mainly relies on that small spherical light sensor at the top of the windshield. If it's covered by dirt or blocked by a dashcam, it stupidly thinks it's nighttime. Another possibility is that the control module under your dashboard has a bug - if it gets stuck while processing signals, it might send wrong commands. There's also an easily overlooked spot - check if the light stalk was accidentally switched to manual mode. Even shifting the automatic gear lever to the manual headlight position can cause them to stay on. I recommend turning off the engine and observing for 20 minutes - if the lights remain on, it needs attention. In my case, I just cleaned the sensor with a wet wipe and it worked normally the next day. Otherwise, you'd need to visit the dealership to check the module's data stream with their computer.
