As of 2017 all Hayward transformers include a Snubber in the box. Always install a snubber on all ColorLogic 12v lighting applications, regardless of the controller and/or existence of GFCI circuits.

A snubber is a plastic-film, high voltage capacitor that will suppress or snub the voltage spikes in electrical systems, such as the inductive kick from a transformer attached to a switch.

The snubber will keep the ColorLogic Lights from falling out of sequence with each other.
