Lamps, Reflectors and Electrical Equipment — 40.0% of failures
Lamps, Reflectors and Electrical Equipment issues account for 40.0% of MOT failures on the Proton Persona Lsi. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail.

Replace any blown bulbs before the test.
Tyres — 28.0% of failures
Tyres issues account for 28.0% of MOT failures on the Proton Persona Lsi. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure.

Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
