I was amazed to see the lights on the pool sign actually change color. Goes great with other kits that are plainer as this one offers some color changing lights. My only critique is that some of the lights wires are ran through all floors and the length of the wire between floors is tight. If its a model like it is for me, not a big deal once you have it all together, little harder when working to set it up. The PRO to the way this is wired is, if you are using switches to the individual USBs, then you can have either outside or inside lights lite.
