Q: Where Is the Headlight Sensor Typically Located?
A: The headlight sensor supports the driver’s field of vision by automatically adjusting or turning the headlights on when it’s getting too dark outside. It can also turn off the headlights to conserve battery life.
If your car has a sensor, it could be on the windshield next to the rain sensor (behind the rearview mirror) or on the dash near the windshield edge. The location differs depending on the model, as some vehicles don’t even have one.
One way to tell if your car has a headlight sensor is to determine whether the headlights automatically turn on or off in response to the environment’s lighting conditions.
Tips on How to Access the Headlight Sensor
Because the sensor needs to detect the road, it’s usually located in plain sight. Check the windshield for something circular that resembles the lenses of your camera’s phone. If it’s not there, check behind the rearview mirror or on the dashboard near the windshield edge.
If your windshield is chipped, assuming the sensor is located there, replacing the sensor isn’t always necessary. However, if the crack is significant, then it might be best to replace the sensor, along with any technology systems attached to the windshield.
You can also check the attached wiring to make sure it’s not damaged or if you want to replace the sensor. Remove the radio and look for the wires that have foam around them for access.
