Banner Engineering TL50 Basic Andon Tower Lights are available with 3 or 4 color segments, with or without omnidirectional audible. Andon lights are designed to enhance and improve industrial workstations, and they eliminate false indications from ambient light using translucent segments to display no color when off. The rugged one-piece design ensures these lights are easy to install, and the operator control box features status LEDs to mimic the tower light above. Banner Engineering TL50 Basic Andon Tower Lights are available in 4 colors: blue, green, yellow, and red.
