Large numbers of motorists could be entirely oblivious to the fact that one or more of their vehicle's light bulbs has stopped working, according to a new study.
Of the more than 2,000 drivers surveyed, 35 per cent said one or more of their light bulbs had blown in the last year.
However, as many as 39 per cent of these drivers only realised their bulb had broken after somebody else mentioned it to them.
Driving with a non-functioning bulb can be dangerous and cost a significant amount on car insurance or result in an MOT failure, but this statistic suggests many drivers are unaware their bulbs may not be working.
Of the motorists who did not realise their bulbs had blown, friends had told 23 per cent of them, other drivers told 8 per cent of them and 3 per cent were informed of their bulb problem by the police and given a fine.
A good way to spot whether your lights are working properly is to check in the car's reflection, as 17 per cent of the motorists who noticed a problem did in the survey.
Another 14 per cent noticed a problem because of the car's inside warning light and 13 per cent recognised a smaller amount of light emanating from the vehicle at night.
As many as 41 per cent of males had suffered a blown bulb compared to 28 per cent of females, the Kwik Fit research found. However, it seems women are usually less aware of car light problems as only 35 per cent of males relied on others spotting their problems while 45 per cent of women did this.
