   I'm glad you got it working as you want it. It's a clever   
   approach.   
      
   There is another way, but it is limited to those who   
   have experience in electronics, and it is limited to   
   only those motion sensors that can be accessed without   
   destroying the assembly. In addition it applies to a   
   specific type of circuit that you must be able to   
   identify based on inspection.  (It would be a whole   
   bunch easier if you had a schematic, but that is   
   extremely unlikely.)   
      
   The method: find the latch circuit and defeat it. In   
   the one I have it is two transistors. Adding a 6.8K   
   resistor from the base of one of them to ground was   
   all I had to do. All functions work as normal, except   
   that a brief power loss does not "program" the lights   
   to be always on.   
      
   If it was easy to do, I would recommend it.   
   I do not recommend it.   
      
   It was, however, and interesting challenge.
