Fog lights are not daytime running lamps

It is difficult to understand, sometimes, how some cars pass the technical tests that allow them to be sold. While I understand and appreciate that daytime running lights have valid safety benefits, as the Swedish manufacturers have proved for decades, I do not need my eyeballs scorching by a strip of blazing LEDs to announce that a car is approaching.

Without trying to turn into GEM’s very own Victor Meldrew, it seems that some owners of older cars that were not equipped with daytime running lights from new have adopted instead the stance of having their front fog-lamps blazing in all weathers. Not only is this inconsiderate but it also flouts the Highway Code, which states:

“You MUST NOT use front or rear fog lights unless visibility is seriously reduced, as they dazzle other road users and can obscure your brake lights. You MUST switch them off when visibility improves.”

You are also breaking the law. The Road Vehicles Lighting Regulations 1989 prohibits the use of front and rear fog lights to dazzle other drivers, when visibility is neither reduced, nor when the vehicle is parked. As fog lights can cause extra dazzle, due to reflections in the wet, they should also not be used in wet conditions.
