Toyota Aygo: lighting & signalling MOT failures
Of the 1,428,093 Toyota Aygo MOT tests in this dataset, 8.3% recorded at least one lighting & signalling failure. It shows up most on 2005 and 2006 cars.
Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair cost: £10–£150 (rough UK ballpark, not a quote).
