What this shows

These are MOT fail items that exterior bulb replacement fixes, as testers found them on the day of the test. Repairs done between MOTs never show up in MOT data, and mileage is not taken into account, so this is not how often owners pay for the repair.

By age

Fail items fixed by exterior bulb replacement, per 100 MOT tests, against cars of the same age and the same fuel mix. The model figure is a floor: DVSA data lists each model’s 25 most recorded items per age, and an item outside that list is counted as zero. The comparison figure is a ceiling: an item too rare to be listed for a fuel is counted at its highest possible value.

How we decide: a page exists only when the main generation’s rate, weighted to its own mix of ages and fuels, is at least 1.5 times the rate of cars of the same ages and fuel, from at least 50,000 tests at 3 or more ages, with at least 100 expected items.

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.
