Use of other lamps during the daytime.
Drivers of vehicles that are not fitted with DRL are not required to turn on their
headlamps or position lamps during the day unless visibility is very poor.
However some European member states do require some form of lighting
during the day so if you travel abroad and do not have DRL fitted you may be
obliged to drive with your headlamps on.
Good God!
Halfrauds have got it right - for once!
But I would add that several non-member states require lights too.
