Has there ever been a suggestion to introduce red lights to police vehicles such as some other countries use. I know the regulation don't permit forward facing reds, but the same regulations exist in NZ, Aus and the USA among many, and they use red lights.
In Some places, New Zealand, Queensland, California for example only police can use blue, but they are used in combination with red which all other emergency services use. That way fire and Ambos are still able to use reds and sirens to respond, but any vehicle showing a blue light as well is Police only and can pull vehicles over.
Just an Idea, but if UK police added reds to their light bars it would make them stand out immediately from all the other blue light users (including HATO's when they get them

)
