2.6 million vehicles with faulty lights
A study across 10 major UK cities, quoted on the IAAF e-bulletin, revealed that some 10.1 per cent of vehicles checked in were found to have a failed headlight, sidelight, rear or brake-light; a proportion equating to some 2.6 million vehicles on UK roads right now.
The scale of the problem is also reflected in MOT failure rates with 1.16 million cars tested in 2012 falling short of required standards because of the condition of their lights.
