It's not so hard to do.....
All manufacturers have the ability to just have the lights on all the time as the law is the same in Scandanavian countries. Hence Volvo's and Saab's more often than not having day running lights on all the time. My 440 has them on as soon as you start the car. When it was bought in in the Scandanavian countries early morning accidents plummeted, and given the amount of spacktards I see in the rain and dusk with no lights on I think this is long overdue. It isn't going to suddenly make all lights blend into the background is it though (bikes)!
I agree it would be barmy if the police are forced to enforce it on older cars. Fair enough any new car sold in this country with the same set-up would be fine but it would be a waste of time. They don't enforce light laws anyway, with the amount of idiot driving around with front fog lights on all the time! But I agree with the idea of day running lights.
