Super bright, cheap, and small bike light!

 I lost my bike light a while ago, and now with shorter days aproaching i will have to ride my bike to school in the dark and at night more often. So thats where the homemade one comes in. I wanted to make a bright, yet clean looking, and compact light. The total cost is VERY low (may be higher if you dont have the battery and charger...but i already had them laying around) below you can see the before and after from the stock light to the finished one(both pics are taken from the same spot and in complete darkness):

Step 1 Materials:

Materials:
-small generic flash light
-krypton "kpr112" bulb from radio shack
-some wire that has the positive and negative connected together(if that makes sense) like an old light plug, or speaker wire.
-sport bottle
-7.2v battery and charger + male connector
-solder equipment
-hot glue
-electrical tape
-some miscillanious screws
-a handle bar mounted reflector
-a heat gun or stove

Cool. Most of those generic flashlights have terrible reflectors, but a few aren't too bad, and they take Maglite bulbs. You can even use a NiteIze $5 LED and it will probably run literally for days with that battery. Thanks. I was thinking of doing this with a cheap flashlight and drill batteries, for one of my road bikes.
