My car failed its MoT because replacement door mirror has no indicator. Why?

Your motoring problems solved


Q. There were originally indicators on the door mirrors of my 2005 Honda Jazz. After an accident I replaced the nearside one with a mirror without an indicator. This has now resulted in a MoT test failure. Why did this happen?

A. As well as the main indicator lamps at the front, all cars manufactured since 1986 must have at least one indicator lamp on each side — known as a side repeater. The only exception is if the car has wraparound front indicators visible from both the front and the side. On some vehicles the side repeater is in the centre of the front wing; increasingly, though, the door mirror is the preferred location. Your tester is correct: you need a new door mirror that includes an indicator.

You could see whether a dismantler in your area can supply a cheap wing mirror from a scrapped Jazz, although this could prove difficult as glass and mirrors are likely to be broken on any accident-damaged vehicle.

Alternatively, try a specialist aftermarket supplier such as Car Shop (, which is listing mirrors at between £53.99 and £71.99, depending on the exact specification.
