Trex Lighting Transformer -INVMISC or other railing systemLighting transformers include a 12v DC transformer that will plug into a standard wall outlet (or the timer), plus a timer and pigtail wire. Timer can be set to turn on at dusk for a certain amount of time, or manually be turned on off. Pigtails convert the large transformer plugs down to the mini plugs that run to each wire. If a remote dimmer is desired, it can be connected between the transformer and the pigtail.
