Picture of Color changing nightlight bulb
In this instructable I will show you how I made a simple color changing light bulb night light. This is the first project in a series of projects featuring low cost color changing LEDs salvaged from  tealights that can be purchased at big lots.

Some background on the tealights
Each tealight has a color changing led, a cr2032 3v battery, a battery holder, and a waterproof case for it all to sit in. Each package of lights contains 2 light assemblies and 2 extra batteries. All together there is:
4x cr2032 3v batteries
2x color changing leds
2x battery holders
2x waterproof cases
In my humble opinion that's a pretty dang good deal for $2
