Where is the automatic headlight sensor located on the MG5?
2 Answers
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.
