How to Tell What Accessories Are on Your Windscreen

When it comes to windscreen replacements or repairs, not all glass is created equal. Modern vehicles often have a variety of windscreen accessories that impact safety features, connectivity, and even how the replacement is done. At Autoglass Warehouse, we’re here to help you identify these accessories so you know what’s on your windscreen, and why it matters.
 

Why Windscreen Accessories Matter

Knowing what’s on your windscreen ensures we replace it with the correct glass and re-calibrate any technology correctly. Incorrect replacements can interfere with safety systems or lead to insurance issues. That’s why Autoglass Warehouse always asks for details, and we can help you check what’s fitted.

Common Windscreen Accessories

Here are the most common accessories you might find on your windscreen:

1. Rain Sensor (RS)

Usually a small square or circle behind the rear-view mirror. It automatically activates your wipers when it senses rain.

2. Forward-Facing Camera (ADAS Camera)

Used for lane keeping, automatic braking, or adaptive cruise control. Usually housed behind the rear-view mirror.

3. Heads-Up Display (HUD)

Projects your speed or navigation info onto the windscreen. If your car has this, the windscreen will be specially treated to allow projection.

4. Light Sensor

Often combined with the rain sensor, it triggers your headlights to turn on when it gets dark.
 

5. Antenna

Some vehicles have antennas integrated into the windscreen for radio, GPS, or mobile reception, look for thin wires or lines embedded in the glass.

6. Heated Windscreen

You may see very fine lines across the windscreen, these are the heating elements, ideal for quick demisting. On the dashboard or climate control panel, look for a button showing a windscreen icon with wavy arrows or similar.

7. Acoustic Layer

Not visible, but you may hear the difference, this laminated layer reduces noise from outside.
 

8. Lane Departure Warning Sensors

Often integrated with the camera, they monitor road markings and alert you if you drift out of lane.
