Did you know that in Pennsylvania, a flashing blue light on a vehicle is a firefighter responding to an emergency? We don’t use these in any non-emergency situation. Even though this is only a “courtesy” light, please give us the right away whenever possible because you never know if we are going to help any of your family or friends who may be in danger. In so many situations seconds do count and being able to get to the emergency quicker really can save lives!
