Introduction: How to Make LED Headlight for Bicycle Using a Bottle.
There was need for a headlight for my Bicycle and could not find one in stores, so I decided to build one myself.
Step 1: Materials Required.
2Ltr Empty Pepsi/Coke Bottle -1pc
1W LED Light -1pc
Torch Reflector -1pc
Resistor 220K/1W or .5W -1pc
Toggle Switch(any switch will do) - 1pc
Screws - as required.
Some wire, Paper cutter, scissors, Insulation Tape, Soldering Iron(if you don't have one you get it soldered from a friend or a mechanic.
Step 2: Cutting the Bottle
Cut the upper part of the bottle as shown in the picture.
Step 3:
Once the bottle is cut make a hole, this will hold our toggle switch.
Step 4:
Screw up the toggle switch as shown.
Step 5:
Fit the LED into the reflector. Also solder the 220k resistor.
Step 6:
Connect the wires as shown in the circuit diagram.
Step 7:
Once done, insert the reflector into the bottle.
Step 8:
Now tape it firmly using the the insulation tape.
Step 9:
Now it should look something like this.
In case you don't have a battery pack. You can use 4AA sized batteries jut remove the resistor and connect the batteries directly.
