My understanding is that the regulations only apply to new models which come out after the regulation is issued, otherwise manufacturers would have to stop selling their current stock and change their design and production process. No way the industry would agree to that!
I believe the latest one states that running lights should come on with the ignition and go off when other lights are turned on. If you fit them now, to a model that didn't previously have them, you will be required to meet the current regulation.
