Times recorded adds every DVSA code with this wording, so a test can record it more than once, for example on two wheels under separate codes.

What it means

This is a major defect: the car fails its MOT. A major defect may affect the car’s safety, put other road users at risk or harm the environment. The car fails its MOT and the defect must be repaired.

Before it reaches this point, testers often record it as an advisory: Individual direction indicator slightly discoloured.

Every lamp is checked for whether it works, its colour, its condition and its aim, along with the battery, wiring and dashboard warning lamps. Many lamp defects are quick fixes such as a bulb, but some point to a fault in a lamp unit or the wiring.

The MOT inspection manual describes the defect (section 4.4.3) as:

Lamp emitted colour, position or intensity not in accordance with the requirements

Read this section of the MOT inspection manual on GOV.UK

The DVSA codes counted on this page: the manual item and the defect text as DVSA records them. The heading above joins the two, as a certificate does; the tester also adds the position, such as nearside front.

Models that get it most

Each model generation is compared with cars of the same ages and fuel, so older and diesel models are not penalised for their age or fuel. Generations are never pooled.

Model generations with the highest rate as a fail, against cars of the same ages and fuel. A model’s figure counts this defect only at ages where it is among that model’s 25 most recorded items, and as zero elsewhere, so it is a floor. Tests (n) are all the generation’s MOT tests at ages with at least 1,000 tests each; at least 5,000 in total.

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.

Repair and cost

The usual repair is exterior bulb replacement, priced per bulb.

Median price (78 shops)£3.99
Middle half of prices£2.50 to £7.99

ONS price quotes for “CAR BULB 12 VOLT SPECIFY WATTS”, September 2025 to August 2026, UK, 1,677 quotes from 78 shops, priced per bulb. This is the price of the bulb. Some cars need a bumper or wheel-arch liner removed to reach it, which adds labour, and many newer cars have sealed LED lamps with no separate bulb. Consumer prices as quoted.

If a garage also charges labour

Local garage labour, per hour (65 shops)£78
Local garage, middle half£70 to £96
Main dealer labour, per hour (62 shops)£156
Main dealer, middle half£144 to £174

Median hourly rate charged for car repairs, from 1,058 local garage and 953 main dealer price quotes collected by the ONS, September 2025 to August 2026. The same shops are priced each month, so the number of shops is the real sample.
