| But it is not only at night that lights save lives, according to the European Commission, which believes that up to 2,000 road fatalities could be prevented each year in Europe, simply by making daytime driving lights compulsory. | But it is not only at night that lights save lives, according to the European Commission, which believes that up to 2,000 road fatalities could be prevented each year in Europe, simply by making daytime driving lights compulsory. |
| Critics insist efforts to do so are motivated by a greedy industry eager to sell more lights and light bulbs. They say modern lights risk blinding other motorists and might draw attention away from pedestrians and those on two wheels, thus making it more dangerous for them. | Critics insist efforts to do so are motivated by a greedy industry eager to sell more lights and light bulbs.

| The UK in particular was opposed, as "motorcyclists in Britain have a habit of using headlights during the day", observes Peter Rodger, chief examiner and head of driving standards at the Institute of Advanced Motorists. | The UK in particular was opposed, as "motorcyclists in Britain have a habit of using headlights during the day", observes Peter Rodger, chief examiner and head of driving standards at the Institute of Advanced Motorists. |
| But in spite of vocal opposition, just under a year ago, on 7 February 2011, the Commission made it compulsory for all new cars to be equipped with daytime running lights that switch on automatically when the engine is started. The same will be the case for new trucks from August 2012. | But in spite of vocal opposition, just under a year ago, on 7 February 2011, the Commission made it compulsory for all new cars to be equipped with daytime running lights that switch on automatically when the engine is started.

| In other words, it could take decades before the number of deaths on our roads is reduced as a result of better car lights - or indeed before the number of bikers hit in so-called Smidsy (sorry, mate I didn't see you) accidents as a result of them becoming less visible in traffic. | In other words, it could take decades before the number of deaths on our roads is reduced as a result of better car lights - or indeed before the number of bikers hit in so-called Smidsy (sorry, mate I didn't see you) accidents as a result of them becoming less visible in traffic. |
| In the short term, drivers keen to see see the road ahead better can fit extra bright light bulbs that offer 80% more light than ordinary halogen ones, or even Xenon upgrade kits that deliver some 300% more light. | In the short term, drivers keen to see see the road ahead better can fit extra bright light bulbs that offer 80% more light than ordinary halogen ones, or even Xenon upgrade kits that deliver some 300% more light. |
| But with bulbs costing up to £85 each, it seems unlikely that we will see a massive upgrade wave anytime soon. | But with bulbs costing up to £85 each, it seems unlikely that we will see a massive upgrade wave anytime soon. |

| At a recent Audi event in Gloucestershire on a gloomy winter's day, it is obvious that such LED lights do more than just improve the visibility from within the car, however. | At a recent Audi event in Gloucestershire on a gloomy winter's day, it is obvious that such LED lights do more than just improve the visibility from within the car, however. |

| Hence, a car using LED lights during the day will use less fuel and reduce carbon dioxide emissions to the tune of 2.5gm per km - equivalent to a 1-3% reduction in emissions - when compared with a car that drives about with its low beam headlights on, Mr Plancke claims. | Hence, a car using LED lights during the day will use less fuel and reduce carbon dioxide emissions to the tune of 2.5gm per km - equivalent to a 1-3% reduction in emissions - when compared with a car that drives about with its low beam headlights on, Mr Plancke claims. |
