Step 1: Go Get the Bulb!
Go to a one dollar shop like DOLLARAMA, buy a FM radio receiver with $1(taxes extra, of course). It has a bulb (3V) which doesn't have much use with the radio.
Step 2: Take Out the Bulb.
Use a precision screwdriver to open the back cover of the radio. Find the bulb and use your iron take it off the PCB.
Step 3: Prepare the New Bulb.
1. Unscrew the flashlight and take the broken bulb out. Carefully unloose the glass part from it's base. I was lucky because the bulb was loose already due to the shock when it fell. If you have problem do that, probably you have to drop you flashlights several times. :-)
2. Use your iron seperate them and make a hole on bottom tip of the bulb base. Keep the bulb base.
3. Rip a 1/2" long insulation from a small gauge wire (22AWG?) and put it on the longer leg of the bulb.
4. Assemble them together.
You're almost done.
Step 4: Your Flashlight Is Back! and Enjoy the FM Music!!!
Put the bulb back into your flashlight. You may need to adjust the focus position of the bulb to get the best result.
Now you're done! Your flashlight is back to life and you, enjoy the FM music!!!
