Choosing between two 3-color LED stack lights
When you need a red/yellow/green stack light to show machine or process status, the decision often hinges on the power setup and what's included. One option is a 3-stack LED Andon tower; the other is a simpler signal light. Both use LED light stacks, but they differ in listed price and included hardware.
Quick verdict
For a more complete kit, the 3-Stack LED Andon Tower Light is the stronger choice. It bundles the extra hardware you might otherwise need to buy separately. For a simpler signal light, the Industrial Signal Tower Light is the more direct option, especially if you want a straightforward setup.
| Product | Listed Price | Price Bar |
| 3-Stack LED Andon Tower Light, Industrial Warning Signal Light 120V-24V Adapter | USD 71.99 | |
| Industrial Signal Tower Light - 110VAC 3-Color LED Stack Flashing Warning Light | USD 31.56 | |
The listed prices sit at opposite ends of the range: the Andon tower is $71.99, while the simpler signal light is $31.56 - a gap of $40.43. That gap reflects a difference in what comes in the box. If you are setting up a new workstation, that difference can determine how much extra wiring and mounting hardware you need to source separately.
Where each product wins
The Andon tower wins when you want the included adapter and 16-ft extension cable. Its listing also describes a PC lens, ABS housing, and aluminum alloy pole, plus an ABB switch and Off/On/Flash modes. That's a more turnkey package for a production line.
The simpler signal light wins on audible signaling. It includes a built-in buzzer, a remote control, and a mounting bracket, with a table mount type. It's a leaner setup that still covers visual and audio alerts.
Product notes
3-Stack LED Andon Tower Light, Industrial Warning Signal Light 120V-24V Adapter

This is the kit-style option for industrial workstations and production lines. It includes a Mean Well 120V-24V adapter and a 16-ft extension cable, which gives you more placement flexibility than a fixed plug. The red/yellow/green LED stack uses a PC lens, ABS housing, and aluminum alloy pole, pointing to a durability-focused build. An ABB switch and Off/On/Flash modes are listed, so you can choose steady or flashing operation. The listing describes this as a 3-stack Andon tower with a red/yellow/green model. One limitation is the condition: it is listed as new open-box, so the packaging may not be factory-sealed.
Industrial Signal Tower Light - 110VAC 3-Color LED Stack Flashing Warning Light

This is the 110VAC option with an audible edge for machine tools, special machines, and robots. It includes a built-in buzzer and a remote control, so you get an audible alert plus remote switching. The red/green/yellow LEDs can flash, and the package includes a mounting bracket with a table-mount type; the model is LTJA-502WJ. The description also mentions a 2W LED power draw and a metal/plastic construction. Because the power source is corded electric, the mounting location will generally need an AC outlet nearby. That's the main trade-off for its simpler corded setup.
Final choice by use case
In short, buy the 3-Stack LED Andon Tower Light if you want the more complete kit. Buy the Industrial Signal Tower Light if you prefer the simpler, direct-signal option.
