My strobe lights.

I carved holes into my foamular board to house the strobes. These are the lights that you put in your carved pumpkins to light it up. They are perfect for this and battery operated and have a simple switch that my son, should be able to turn on, when he opens the lid of my future box. This foam , I'm planning to glue to the lid. I'm still debating if I should line the sides of the box with mirror to really let the lights make magic.
