Piwoslaw, In France (Europe ?) DRL are mandatory only on brand new cars sold since 2010/01/01. Since 2009 summer, Audi are sold with these LED DRL, but I have to confess that I hate them, they are making you focus on them and so distract you from what you should be looking at, noticeably when you are on a multi-lane road protected from the cars in the opposite lanes.

Nevertheless, this is a great idea to place them there as they effectively improve a dirty aerodynamic place. Sadly all the LED strings I can find nowadays are very expensive and I'm not sure that I will not distract people coming in front of me.

In a safety point of view, this will improve only in very specific cases and while not all cars have them. As soon as all the cars have them then it will not work anymore. At the same time motorcycle that have them since years will then "disappear" and will have their safety lowered. This has been the case a few years ago when several places in France did the experiment to have lights on all day long, the number of accident by cars against motorcycles increased significantly.
