   Thermostat controlled flasher is probably the exact description. It   
   happens when LEDs are driven straight from batteries too, and is   
   probably the bond wire heating and cooling making intermittent contact   
   at a few Hz.   
      
   I have a cheap LED torch which uses nine parallel connected white LEDs   
   running directly from 3 AAs.  After a battery replacement, one is out,   
   four flash at different rates, and four are on.
