Hard to predict in isolation — depends what's actually worn.

This defect doesn't map to a clean retail-part swap; ranges vary too widely without seeing the car. Use the estimator to bracket the all-in cost across the items most likely to surface alongside it.

Frequently asked.

Why does product on the lens or light… fail an MOT?
Product on the lens or light source which obviously reduces light intensity or changes emitted colour to other than white or yellow. Most commonly flagged on the Toyota Previa. The DVSA's MOT standards require this item to meet minimum safety thresholds — when it falls short, the tester logs it as a Major or Dangerous defect and the car fails outright.
How much does it cost to fix product on the lens or light…?
Costs vary depending on the vehicle, region, and severity. Use our MOT cost estimator for typical UK garage rates across the most common failure items.
