FLEET managers are being warned to advise drivers to check their lights on company cars as the winter nights draw in.

Studies from the AA show almost half a million drivers have defective lights which can cause confusion for other drivers.

Faulty lights can make it more difficult for other drivers to judge gaps, and give less time to react when traffic slows.

Driving with a faulty light could lead to a fixed penalty notice or three points on a driving licence and an increased fine if proceedings go to court.
