Akasa Power Eyes
 

The Power Eyes come in a set of 5 in the retail package shown. You'll need to snap the pieces apart before inserting them into your connectors. Two versions are available: blue and "rainbow": one each of blue, green, orange, red, and blue/red. Instructions can't get any simpler, as shown on the back of the package. You insert the PCB into a male connector, then plug in the female connector and enjoy the show.
