These goggles were my first GB prop I built last year. Went cheap and just had some fun!
I’m going to be wearing my GB uniform around town on Halloween and since I don’t have a pack yet I thought I need to add some flash. I added an extra band on the back to go over my head. I also found a flashing LED from a toy package I had laying around. I drill a hole and added the LED onto the front. I think people will get a kick out of it on Halloween. 
Now, to get that pack built.
