ANDONT 3-Stack LED Andon Tower Signal Light with Buzzer, Red/Yellow/Green, On/Off, Plug-and-Play

Got it as a prank at work, turns out people love it. Red means stay out of my office,green means come on in, yellow means I am busy, but available if needed. Love it

Each color of light is controlled by its own switch, and 2 or 3 can be on at the same time. The switches feel very robust and durable. The light isn't super bright, but it's bright enough for most use cases I can imagine. The buzzer is plenty loud enough to be used in a lot of factory environments, though maybe not all.If you remove the clear plastic light cover, and then the white plastic light cover, you can access the 4 dip switches that control the flashing vs steady-on light behavior. Supposedly, you can also turn off the red light buzzer. However, my switch my have been defective as there was no position of any of the switches that would turn the buzzer off. It's easy enough to unscrew the circuit board and clip the buzzer wire though, if that's of interest. They probably usually work, but mine did not. The dip switches are very small, and you'll probably need a tool to move them.Easy to install and use, less easy to change light and buzzer settings. Though you probably won't have to change them again once you get them set the way you want.

It's an interesting light stack. It's all self-contained. So you got a light. You got switches and you got a power supply the whole thing is manual. You twist the switch to turn on the light you want. You can turn on multiple colors so turning on the yellow and green makes kind of this lime green turning on the yellow and red. Makes an orange turning on the The red and green makes a dark orange. It don't quite get the whole setup. I suppose it could be used to manually indicate conditions. I will probably end up taking the whole thing apart using the light separate from the switches. I'll probably use the power supply with the lights and then use relays to switch on the individual lights. I'm thinking for like a sump pump alarm. That's what I ordered it. Thinking to use it for but the whole thing is kind of weird. I do like it though. I think the quality of the components is pretty high. The buzzer or beeper if you will is loud but not obnoxious

To turn off the beeping sound, the instructions say to make this change on the circuit board, however, you will find that this does nothing. Other reviewers have commented the same.Solution: unscrew the circuit board (there are two screws holding it down) and cut off the wire leading to the beeping element. You will find it once you unscrew the circuit board. It's easy, but does take some skill to understand the wires beneath the board.All else with this product works well, except the inability to turn off the beeping.

Super easy to mount!Great power connection on the bottom fit our existing poles perfectly.I love that you can pick solid vs. flashing by individual color!Only issue was the buzzer.I could not turn it off with the dip switch.So I cut the buzzer wire, and problem was solved!Good Andon light!
