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.
