Wing mirror glass: types, replacement and how to choose
Cracked or loose mirror glass is the cheapest wing mirror fault to fix, if you order the right type.
What is wing mirror glass?
Wing mirror glass is the reflective plate that clips onto the backing plate inside the mirror housing. It is the part you look into. If the housing, motor and indicator work, replacing only the glass is usually the cheapest repair.
Types of wing mirror glass
| Type | What it is | Where you see it |
|---|---|---|
| Flat | Gives an accurate sense of distance | Often on the driver's side |
| Convex | Slightly curved for a wider view | Often on the passenger side |
| Aspheric | Flat in the main area, curved at the outer edge to cut the blind spot | Common on many newer cars |
| Heated | Has an element on the back that clears frost and mist | Many mid and upper trims |
| Auto-dimming | Darkens to reduce glare from headlights behind | Some higher-spec cars |
| Blue tint | Reduces glare slightly | Some cars and aftermarket glass |
How to choose the right glass
- Pick the correct side. Left and right glass are different shapes. In Ireland, right is the driver's side. See wing side mirror.
- Check for heating. If the back of your old glass has two small connector tabs, it is heated, and you need heated glass.
- Match the shape type. Flat, convex and aspheric glass are not interchangeable.
- Check special features. Auto-dimming or blind spot warning glass needs the correct type.
- Confirm your car. Make, model and year matter because glass shapes change between generations.
When glass alone is enough
Replace only the glass when it is cracked, scratched or has fallen out, and the housing, motor and indicator work. If the backing plate is broken or the motor has failed, you will probably need a full unit. See glass vs full unit.
Fitting new glass
Most glass clips on in a few minutes. Our step-by-step guide explains how, including connecting the heater wires. If the glass keeps coming loose, read wing mirror glass keeps falling out.

Frequently asked questions
How do I know if my wing mirror glass is heated?
Look at the back of the glass. Two small connection tabs with wires mean it is heated. A heating symbol near the rear screen heater button is another clue.
Can I fit flat glass in place of convex glass?
It may physically fit, but it changes your view and may not suit your car. Replace like for like.
Is the left and right mirror glass the same?
No. They are mirror-image shapes and often have different curvature, so you must order the correct side.
