Mitsubishi Colt: lighting & signalling MOT failures
Lighting & signalling was recorded as a failure area in 17.9% of Mitsubishi Colt MOT tests — 29,558 tests out of 164,852. It shows up most on 2004 and 2005 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).
