I've been playing around with lights in editor and think it would be cool if the lights were all blue to match current law enforcement standards and to have a yield traffic control bar. The yield traffic control bar would only be able to be activated while stopped as to prevent scroll wheel cluttering. Also, if you notice in the video it would be better, for safety reasons, if all vehicles/ranks had rear lights too. All the changes shown. Pay attention to the brightness of the old emergency
