"I am interested to know if the Evictor strobe light has any sort of on/off switch on the cord or on the light itself. I can't see from the picture if that is the case. Are there certain types of sun glasses or protective glasses one needs to enter an area with an active strobe light?"

The Evictor Strobe Light doesn't have an on/off switch.  We recommend plugging it into an outlet with a switch, or using a surge protector with a switch.  You don't have to wear sun glasses, but please avoid looking directly at the light when it is turned on.
