Introduction: LED Strobe Pumpkin Decoration for Halloween for Only $3
Go down to the Dollar General and buy 3 things
A Carvable Pumpkin
An LED Strobe Light
and AA bateries
Step 1: Carve It
Now cut the top open enough to fit the LED strobe light into the pumpkin.
You can even carve a face into it if you want. I didn't carve a face into mine yet because I liked the way it lights up the pumpkin.
