Shutter Shades are made with a Sturdy White Frame.
The Light controller takes 2 AA batteries and has 3 settings: All On, Fast Blink, and Hyper Strobe.
The battery pack can clip to anywhere on your upper body. I clip it to my belt or put it in my pocket.
Don’t buy cheap knockoffs that use 2 watch batteries. They often only last 15 minutes before dying!
