Its the cars theft deterrent system. A few weeks ago, someone wrote in asking about it. They had taken it to the dealer, who had run diagnostics and told her the car was ok. They didnt tell them it was normal though, and she was scheduled for more tests! Look in the owners manual, page 107 if I recall correctly. It supposed to scare thieves, not the owners!

It's for the immobilizer system (look it up in your manual), and it's normal. The light flashes after the "Power" button has been turned off to indicate that the system is operating. The immobilizer system is designed to prevent the car from starting if a key hasn't been registered with the car's computer. As someone else wrote, the light is a warning to thieves not to bother. All of this is on page 116 of my 2012 Prius V manual.
