Testing an automatic headlight sensor requires the use of a few tools and materials. To begin, you will need to have access to a 12-volt power supply and a multimeter. Additionally, you should have some insulated wire on hand for connecting the components together safely.
Once these items are gathered, connect one end of the insulated wire to the positive terminal of your 12V power supply and then attach it to one side of your multimeter’s leads. Next, disconnect the headlight switch connector from its socket in order to gain access to each pin inside. With all connections made, carefully measure each connection point with your multimeter while turning on/off your headlights manually or via auto mode if available.
The voltage reading should change depending upon which setting is being used (on/off). If everything appears normal with no erratic readings or shorts present in any pins then that means your automatic headlight sensor has passed testing successfully!
- Park the vehicle in a dark area: To begin testing, park the vehicle in a dark environment such as an unlit garage or alley to ensure that no external light sources will interfere with the test results
- Turn on headlights manually: With the engine running, turn on all exterior lights including headlights and fog lights manually to make sure they are functioning properly before beginning testing of the automatic headlight sensor feature
- Set up voltage meter for current draw measurement: Attach a digital multimeter to measure current draw from the battery when turning on various lighting features associated with your car’s automatic headlight sensor system such as parking lamps, dimmer switch settings etc
- This helps determine if there is any issue with power being supplied to those components while using this feature
- Adjust sensitivity setting of headlight sensor: Using your car’s control panel, adjust the sensitivity level of its automatic headlight sensor so it is set at its lowest level possible without completely disabling these features (i
- , minimum brightness)
- This step ensures that even in low-lighting conditions, external illumination won’t trigger false activation of your car’s headlights and other exterior lighting elements unnecessarily
- 5 Cover sensors and observe response: Once you have adjusted sensivity levels appropriately cover each individual light sensors one by one (such as windshield mounted sun-sensors)
- Observe changes in output – If everything works correctly then you should see corresponding decrease/increase in brightness based upon which particular sensor has been covered/uncovered respectively at any given time

How Do You Adjust Automatic Headlight Sensitivity?
To adjust the automatic headlight sensitivity of your car, you first need to understand what it is. Automatic headlights are lights that turn on and off in response to changes in light intensity. This helps ensure that the driver has adequate visibility at all times, regardless of how dark or bright the environment may be.
The sensitivity of these headlights can be manually adjusted by turning a knob located either on the dashboard or near the light switch itself. To reduce sensitivity, turn it clockwise; to increase sensitivity, turn it counterclockwise until you find a setting that works best for you and your driving conditions. It’s also possible to make further adjustments with some vehicles, such as changing how long they take before automatically turning off when no longer needed.
