Flashing type: not working
This one item accounted for 0% of every MOT test carried out in Great Britain, and it is among the commonest faults on 31 different model-and-year combinations. Here is where it clusters, and what it looks like on a car you are standing in front of.
How to spot it before you buy
With the seller's help, test every exterior light — head, brake, indicators, reversing, fogs
Failed bulbs fail the MOT; LED/xenon units can be very expensive on premium cars. Needs the key and someone working the switches — save it for when the seller joins you.
The models it hits hardest
Ranked by how often the fault came up as a share of that model's own tests, not by raw count — a fault in 8% of a small model's tests says more about that model than one in 3% of the Fiesta's. A linked row has a page of its own.
