Light Up the Room With These LED Earrings | Make:

Before attending a fancy event, my friend asked me to create her some earrings that would light up. I needed to design something that would be lightweight, but I also wanted it to be wearable without the battery for everyday use. I started with a small 3V coin cell battery and built it out from there by playing around with the LEDs until they fit. This is the design I came up with.
