Step 1: Here is all you need...
Model #IN215WB-S. These are impact-resistant with a heavy-duty casing that withstands a 5-foot drop test on concrete. Resistant to grease, oil, gasoline and solvents. Shock- and corrosion-resistant.
Step 2: Item #2
I chose Duracell Ultra but you can find them CHEAP HERE!
Step 5: EZ Steps...
2. Install the Radio Shack lamp and re-assemble the housing
3. Drill or file down the ridges inside the flashlight to make room for the 123 batteries
4. Install the 3 Lithium Ion batteries and screw on the bottom.
5. Turn it on!
(Optional: I painted mine black satin to make it look like the real thing...and it IS!)
