What is Windshield Windshield Light Sensor System

Windshield night vision is a driver-aid technology that helps enhance road safety by alerting drivers of persons, vehicles, animals, and other obstacles ahead of them. Even with your car’s headlights turned on, you may not be able to see the barriers ahead of you. Most modern night vision systems use infrared radiations to scan and detect any obstacles early and send alerts to your dash, enabling you to stay away from danger.

How Windshield Light Sensor System Works?


The night vision system features infrared and thermal sensors in the vehicle’s grille. Upon detecting any obstacle that may put you in danger, the night vision sensors will alert you and display images on the dashboard or center console screen. Advanced Night vision systems will show pictures of the traffic ahead of you via a heads-up display on the windshield. Both of these types rely on the command prompts of the onboard computer in the center console.

Night vision systems can be helpful, especially during conditions affecting road visibility. The thermal sensors detect IR waves or heat to calculate the distance between your car and the objects, obstacles, animals, or vehicles ahead of you. For example, during snowy and heavy rainy conditions, knowing the safe following distance to maintain enhances everyone’s safety on the road. On poorly lit or dark streets, the night vision system will alert you of what is ahead of you, enabling you to take appropriate action to avoid any possible danger. This system not only scans, detects, and sends alerts about cars but also pedestrians, objects, animals, and other creatures.

Night vision systems may not be present in all modern vehicles. But it’s an important part of any vehicle. Therefore, drivers should check the user manual to be sure and learn how to use the windshield night vision system. Knowing that there is a hot spot ahead of you before you get there will help you to take appropriate action, enabling you to avoid road accidents.

Replacing Windshields Equipped with Light Sensor System

When it is time to replace your car windshield that is Equipped with Windshield Night Vision System, all the cameras and sensors are removed and reattached after windshield installation. A recalibration procedure is then required to ensure that this critical safety system is functioning properly and is performing in accordance to the manufacturer tolerances.

When your car’s Pedestrian Detection System is not properly calibrated after a windshield replacement, the cameras or radar can be misaligned by even millimeters. This could cause dangerous driving conditions and accidents!

Many glass shops try to avoid performing recalibration due to lack of knowledge or calibration equipment. They will simply keep the wires intact, install the new windshield and call it done.

When installing a new windshield, be assured that it will always be off by few Millimeters from the original windshield position.

At Francis & Sons Auto Glass we have the latest recalibration systems and the expertise and experience to recalibrate your Windshield Light Sensor System to its factory setting and we back it up with our lifetime warranty.
