This instructable will show how to take an ordinary Mag-lite flashlight and modify it to hold 12--10mm high-powered LEDs. This technique can also be applied to other lights as I will show in future instructables.
Step 1: Tools Needed
12--10mm High-Powered LEDs (I bought mine from besthongkong on eBay)
Insulated wire (preferably ~20ga)
Thin plastic (preferably clear and flexible, I used PETG from a local supplier)
