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!!!

    i find those types of bulbs EVERYWHERE even a few LED versions

     why not add the radio in to the circuit its self? or take a thumb drive mp3 player cut a hole to view with and power it on the same battery i mean come on leds dont take that much power?

    I think that LEDs make the batteries last longer than bulbs, for me a good reason! Less chemicals in the world.

    instead of buying a bulb or pack of bulbs at the dollar store, you buy a radio that will brake and a take the led that if it was made for a circuit board probably wont last as long as you would think.

    Thanks for all the information. The problem is the Shipping & Handling fee may cost you over $5.

    Nice idea... and cheap/free to boot! Led's lend themselves to this pretty well too... can rip the led outa any old led device (even the remote, if you want a infrared flashlight). just use an inline resistor(of the appropriate value, so it doesn't pop on you) Sadly, this doesn't work well on single cell flashlights ;-(

    Yeah, LED is great because it is shock-proof. I may make one when the current bulb burns out. The regular LEDs is too dim to be practical. I need high power LED.
