The standard LED lantern can be useful at times by providing light and not consuming much power, yet its a little boring. So we will attempt to spice it up with some full on sextuple rainbow LED action.
Step 1: Materials
1- LED lantern
2- rainbow LED (can be found here or here, either should be fine)
Step 2: Open It Up
The first thing you need to do will be getting the lantern open. Now all lanterns will likely be different to open so this step will be different for everyone. With my lantern you have to unscrew the bottom where the batteries are, then there were 3 screw to unscrew (i say were because i seem to have since misplaced one) then it should come open.
Step 3: Soldering
After they are all out, you should begin putting in your new, awesome LEDs. Once you have them all in you should cut off all of the extra leads on.
Once they are all cut you are ready to put you lantern back together.
