Abstract: A signal system for a vehicle has a vehicle mount that is configured to be attached to the vehicle. A power source is arranged through the vehicle mount and electrically coupled to a vehicle power source. A solenoid is electrically coupled to the power source and mechanically coupled to a spring. An arrow main pole is mechanically coupled to the spring, a first head blade and a second head blade. A solenoid controller is electrically coupled to the solenoid. Activating the solenoid controller engages the spring to rotate the arrow main pole approximately 180 degrees in a first direction into an expanded arrangement. Collapsing of this expanded arrangement by hand reloads the rotational energy back into the springs that can produce a future expanded arrangement.
