Sounds good. And yes, vehicles are better than lights for protection on the highway. In CT we have the luxury of arriving after the state police. They always park behind the scene/accident and we would pull ahead of it for saftey. Its not a guarantee (one of our rigs got taken out by a dwi that got scared) but it helps. For the strobe I was leaning more to the scenarios where you are not near the rig.
