When I was a Vol FF, we could run Red Lights, but had to have a siren also. We could keep red lights in our vehicle for scene warning without a siren, but could not drive with it active then. Vilas County, Wisconsin, USA. That was quite a while ago though, so I don't know if the laws have changed now or not. I see lots of Vol FF vehicles around my area, they do have lights on them, and all appear to be Red. When I was a Vol FF, we could run Red Lights, but had to have a siren also.
