Has a thread like this been started yet? Aside from a bit of green on a command vehicle, you really don't see much green or purple out there. I am thinking that it would be fun to have a common thread where we could post pics/vids of green and purple warning lights in their unique service. Will they be on a hearse? Maybe private security or a snow plow? Could there be a tow truck that is just dying to stand out? Let's see what you all can find.
