Emergency Light -  A simple circuit that activates a light when the power is out. A version with a lightbulb and another with white LED light included….
Emergency Light & Alarm -  Powered by2-AA NI-CD batteries Four switchable options (added 6/06)
Failed Power Light -  turns on small low voltage lighting when mains power disappears.....
Low cost/ Automatic Emergency Light -  ….(electronic schematic added 08/08)
Main Fuse-Panel Emergency Light -  The area around the Main Electrical Panel is usual pretty dark, especially if it is located in the basement.  That's during daylight hours.  At night everything is dark during a powerfailure, or tripped circuit breaker, fuse, etc.  This circuit provides ample time to fix the problem..... [Tony van Roon's circuit]
