The master controller is on a card with a stand-off and has sliders for dimming. To accomodate everyone's varying needs for a controller box, the unit is supplied "bare-bones." We supply the electronics, you supply the box.
Reversible steady colors: Red/Green or Red/Yellow.
Looking for a really small LED marker? Try the Quarter Marker. About the size of a quarter, they are very thin and virtually unnoticeable.
Quarter Markers also change color. With the included CR2032 lithium coin cell battery's (+) positive side facing UP, the Quarter Marker will light up red. When you flip the battery over (change the polarity), the LED changes to green! Also available in red-to-yellow.) It's like having two beacons for the price of one.
