Step 1: What You Need:
- A cheap LED headlamp with a flashing/strobe setting
- 3 volt button cell batteries (I used cr2025 batteries)
- A multi-tool or a knife and wire strippers
- Duct tape
Step 2: Dissasembling the Headlamp
- Strip the ends of the battery wires to expose about 1/4" of bare wire. This is a delicate step, since the battery wires are likely weakly connected to the circuit and may break off.
