There's a series of signs with flashing lights on the highway that say something like, "If lights are blinking, tune to 590 AM for emergency traffic information."  One of the signs near my house has lights that are always blinking, traffic emergency or not, which completely nullifies the purpose of emergency flashing lights.  If the lights are always blinking and it doesn't necessarily mean there's an emergency, that means the lights serve no purpose.  It's the same thing with a local fire house, whose flashing lights are meant to signal an exiting truck, but since no truck is exiting, merely serve as "crying wolf" and wasting electricity.  These things remind me of store security alarms that everyone ignores and warnings about chemicals that cause cancer, which are also largely ignored. #psychology
