LED for Dummy Alarm Box

Just had a buglar alarm fitted and as part of the package got a dummy box got the back of the house. I decided to have it mounted on the garage above the door. I am now wondering if I can find a way of fitting a couple of flashing LEDs in it to make it look real. Any ideas on readily avalable stuff that could do this - fed of a wall wart perhaps?
