What it means
This is a minor defect: the car passes its MOT and the defect is recorded. A minor defect has no significant effect on safety or the environment. The car passes its MOT and the defect is recorded on the certificate. It should be repaired as soon as possible.
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 it (section 4.1.6) as:
A headlamp cleaning device inoperative
