This 360º Minleon pebble with clips has 2 diodes on the front and back of the pebble (4 diodes total).  The molded clip is designed to clip onto a quarter round bead, or the Minleon base bracket which the track would normally clip onto.  No track is needed to install this bulb.  This is great for commercial buildings where you can mount the bracket onto the top of the drip edge and clip the bulbs directly onto the bracket above the drip edge.  These are 4-wire 24 volt color changing RGB pebbles.

12" spacing between pebbles.  There are 4 different lengths as follows:

25 pebbles

10 pebbles
