The LED
this step is just preparing the LED for the battery pack and putting it in the case.
The Battery Case.
This is the battery pack for the flashlight. Once you put it in bend the positive lead of the LED so it almost touches the batteries.
The Top
The top is made out of electrical tape with more electrical tape to hold it on. When you push down on the electrical tape, it turns on the LED.
