In a busy shop, a warning light isn't just a light-it's a communication tool. Signaling indicators for operator controls tell a machine tender, assembler, or line lead whether a station is running, waiting, or needs help. The two stack lights here take different approaches: one is a three-tier unit ready to run, the other a multi-layer tower with an audible alert. One focuses on simplicity and a low upfront price, while the other gives you more layers and signaling options. The right pick depends on how many statuses you need to show, how you plan to mount it, and how much you want to spend.
Quick Verdict
For a workstation where red, yellow, and green cover the message, the 3-Stack LED Andon Tower Light at $71.99 is the simpler, more economical choice. Need extra layers and an audible alert? The Industrial Stack LightLED Signal Tower at $89.60 is the more capable option. Both are LED-based and sized for industrial use, so your choice is about configuration and extras rather than basic light quality.

Where Each Wins
The 3-Stack LED Andon Tower Light suits a fixed workstation where the basic color signals are enough. If your station already has a control cabinet and a permanent spot above the line, this is the straightforward pick. The Industrial Stack LightLED Signal Tower suits a more complex or mobile setup. When the light needs to move between stations or be noticed in a noisy area, the multi-layer option gives you more to work with.
Product Notes
3-Stack LED Andon Tower Light
The 3-Stack LED Andon Tower Light is built around the three statuses most workstations need: red, yellow, and green. The included Mean Well 120V-24V adapter and 16 ft extension cable mean you can connect it without hunting for a separate power supply, and the ABB switch gives you a physical way to flip between off, on, and flash modes. Construction uses a PC lens, ABS housing, and aluminum alloy pole, so it feels suited to industrial workstations. The catch is the three-color arrangement; if you need a fourth or fifth status color, this tower stops at three. It is in new-open-box condition, so the packaging may have been opened even though the product is described as new.
Industrial Stack LightLED Signal Tower
The Industrial Stack LightLED Signal Tower stands out for its five-layer configuration, which gives you more color positions than the usual red/yellow/green setup. It accepts DC12V/DC24V/AC110V/220V, so it can adapt to different control voltages, and the buzzer produces 85dB for audible alerts. The foldable design and DIN-mount base options make it easier to move between stations or mount on a rail. Flashes cycle at 60-80 per minute, and the light source uses high-brightness LEDs with an OSRAM lamp for long life. The limitation is the added complexity of configuring five layers and matching the correct layer-to-color layout, especially with the red, blue, yellow, and green arrangement.
Final Choice by Use Case
If your line needs the basic run, ready, and attention signals, the 3-Stack LED Andon Tower Light covers it with less setup. If you're building a more complex cell where multiple colors plus an audible alert keep operators informed, the Industrial Stack LightLED Signal Tower is the stronger match. The trade-off comes down to how much status detail your workstation needs.
