We source each of these LED stoplight modules from a traffic signal company so each is 8" in diameter and very visible! The lights are controlled with our own stoplight controller module which allows you to set each light to on off or flashing. All control methods are supported by this controller so you can configure the light manually with a pushbutton on the controller, with the IR remote, or via our network controller board.
9 levels of brightness
Set Light On, Off or Flashing
Three different flashing speeds
