Step 1: I Want the Green One
Second step take the flashlight apart and gaze at its beautiful simplicity, maybe sheds some tears.
Third step gather parts, Leds, batteries, toggle switch, wire, soldering iron and hot glue gun (every western crafters best friend)
Step 2: Time for Drilling
Take the flashlight reflector and drill about 3 holes or more depending on your LEDs specifications.
I am using 3 Leds I had laying around the house and I will be powering the whole thing with a 9 volt.
Roughly space out where you'd like drill the 3 holes and "drill baby drill," thanks Sarah Palin now go back to watch, baby watch Russia.
Hot glue the LEDs in the holes and position them so the postive (+) and negative (-) contacts alternate. This will make soldering easier.
Step 3: Time to Remove the Switches and Trim the Light
Luckily the orifice (that sounds dirty) fits the toggle switch I had, so I didn't have to widen the hole but you might.
Trim the end of the flashlight down so you can insert an old pill container to hold the 9 volt battery that will power the whole unit.
You don't have to do this but I found these old pill containers at my grandmothers house and after eating all the old pills I saw visions and I had this bright idea.
Step 4: Basic Layout and Soldering
If you are using a on-off-on toggle switch the center 2 contacts are for power. Solder the main power supply to those contacts right now polarity doesn't matter.
Next solder 2 wires to the incandescent bulb to the front 2 contacts on the toggle switch and switch it on to see if it works.
Finally solder together the LEDs in series and solder the 2 wires to the second contacts on the toggle switch. Make sure you check for polarity by switch the toggle switch on to see if the LEDs come on, if they don't just change the wires around on the contacts.
Last step piece to together the LED/Incandescent flashlight like the picture show and hot glue it together.
Step 5: Let There Be Lights
Hope you liked this project, simple and easy... currently working on something more complex. thanks
