This is an instructable on how to make a flashlight out of a ChapStick tube. After reading up on multiple LED instructables I thought it would be neat to make an original design that had not been done before. Since button cell batteries can be expensive, I went with an A23 (12V) battery that cost less than $2.00 for two.
Step 1: What You'll Need:
A23 Battery (12V)
10mm White LED (28,500mcd, 20mA, 3.5V)
Heat Shrink Tubing
"N" Battery Holder
