HAHAHAHA Blue and red is definitely the way how to outfit a emergency vehicle all around. Amber isn't that much visible than you think. Amber is a warning color! Used on trash trucks,... I won't discuss with you longer about that.
No, it dosn't. It just a stupid law. Red & blue lights are better visible, that's a fact. amber lights are good as additional lights in the back of a vehicle, so that you know that it's the rear.
Ich vergleich RTWs in Spanien ja von der Optik her gerne mit sowas wie der Straßenreinigung in Deutschland. Blau oder zumindest rot sollte es obden drauf schon sein.. Aber schönes Video isses trotzdem!
For some reason, they're biased towards red lights and don't like blue or any other colour. I think all blue is better than all amber, and just have amber for warning lights and slow vehicles, but a bit of amber with blue is really effective. All red is bad day and night...
