Where is the automatic headlight sensor located on the MG5?

[EmersonDella]

The sensor for the MG5's automatic induction headlights is located beneath the front radiator grille of the vehicle. Relevant information about automatic induction headlights is as follows: Introduction to automatic induction headlights: Automatic induction headlights, also known as sensor-activated automatic headlights, operate when the central intelligent control unit detects changes in light intensity through a light sensor positioned behind the interior rearview mirror. This system automatically turns the width lights and low beams on or off. Advantages of automatic induction headlights: The headlights can automatically adjust to changes in external light intensity, providing additional illumination before visibility is affected by light conditions (such as entering tunnels or underground parking garages). This requires no manual operation and does not distract the driver.

My MG5 has been running for over two years, and the automatic headlight sensor is located in that small black dot above the windshield, right next to the base of the interior rearview mirror—a circular device with a mesh pattern. During the last maintenance, I specifically asked the technician, and this thing is technically called an ambient light sensor. It detects changes in external brightness through the windshield, automatically turning on the headlights when it gets darker, and reacts particularly quickly when entering tunnels. However, be careful not to cover the sensor area with windshield tint film—my friend’s film was too thick, resulting in the automatic headlights staying on even in broad daylight. When washing the car, remind the workers not to blast this spot directly with a high-pressure water gun, as I’ve heard some owners accidentally loosened the sensor. In daily use, I’ve noticed the sensing range is most sensitive within about 50 meters ahead of the car, and it’s much more convenient than manual switching during dusk.

The automatic headlight sensor of the MG5 is located at the top of the windshield behind the interior rearview mirror, appearing as a coin-sized circular protrusion. I remember the salesperson demonstrated during delivery that covering this area with a hand would immediately turn on the headlights. Once during rain, I noticed it even activates the rainy mode—the low beams automatically turn on when the wipers operate continuously. However, it's worth noting that owners who have modified their front windshield film might experience malfunctions in automatic mode, as metallic films can affect light penetration. For regular maintenance, you can gently clean the sensor cover with a cotton swab dipped in alcohol to prevent dust and oil film from interfering with sensitivity. Tests show that at 60 km/h on city roads with streetlights, the sensor's response time to sudden darkening environments is less than 2 seconds.

The induction zone is located at the top center of the windshield, right next to the base of the interior rearview mirror. This light-sensitive sensor is responsible for monitoring external brightness around the clock, controlling not only automatic light switching but also the automatic headlight leveling function. Special attention should be paid to clearing snow from the sensor in winter, as some car owners have reported fault codes appearing on the dashboard when the sensor is covered by snow. When driving into underground garages during daily commutes, you can clearly hear the 'click' sound of the relay triggering, indicating it's functioning properly. When installing audio systems or dashcam wiring during modifications, remember to avoid this area. I've seen cases where wiring pressed against the sensor caused lighting malfunctions.
