The Chameleon is designed to function as either a steady or flashing visual signal. It is designed such that any or all three lights can be activated by either a PLC or contact closure. The first light activated will illuminate either steady or flashing (set by an internal jumper). If a second light is activated, the Chameleon cycles between the two colors. A third activation causes the Chameleon to cycle between all three colors: red, amber, and green or red, amber, and blue.
