What to weigh before you pick
A signaling indicator on an operator control station has to answer two questions before anything else: how will it be powered, and how many statuses do your operators need to see at a glance? Andon tower lights solve that problem by stacking colored LEDs on a pole, but the four options in this comparison take very different paths. One runs on 5VDC over USB, one uses a 12/24V DC circuit, one runs on 110VAC, and one focuses on a sturdy aluminum pole. The right choice depends on the wiring already at your machine, the number of signals in your workflow, and whether you also need an audible alert.
Quick take
Here is the short version: the 5-Stack USB LED Andon Tower is the USB-powered pick with five color segments and a built-in buzzer; the ANDONT Industrial 4-Stack is the aluminum-pole option at a middle price; the LUBAN 3-Layer is the 12/24V DC buzzer light; and the 110VAC Industrial Signal Tower is the lowest listed price in the group.

Product notes
5-Stack USB LED Andon Tower Signal Light
This is the only five-tier unit in the comparison, with LED segments listed as red, yellow, green, blue, and white. If you are signaling status on a CNC machine, assembly line, or programmable workflow, the extra tiers let you show more than a simple go/stop state. The product description also describes plug-and-play USB power at 5VDC, an 85dB built-in buzzer, an adjustable bracket, and a 9-foot USB cable, which makes it the most self-contained option here when USB is available at the workstation. The tradeoff is the USD 177.99 price, well above the other three, and the California Proposition 65 warning included in the product details is a detail to weigh.
ANDONT Industrial 4 Stack Andon Tower Signal Light, Aluminum Pole
The ANDONT stands apart because it names a specific pole material: aluminum. The four-stack design is meant for industrial automation and motion-control systems, and the description says multiple lights can be illuminated at once, which is useful when a machine has more than one state to show. At USD 40.00, the price falls in the middle of this group. The product details give a model reference, TYDS C-809LZ-57, alongside the New condition, so it is easy to identify the exact unit. The main limit is the price: it is still USD 8.44 more than the entry-level 110VAC tower, so it is not the least expensive way to get a stack signal.
Signal Tower Stack Light 3-Layer Buzzer 12V 24V DC
This LUBAN tower is the one that lines up with 12V/24V DC control circuits. The description points to high-intensity LEDs, a built-in buzzer rated at 90dB, and a design that lets each tier switch between steady and flashing modes. It also carries an IP54 rating against dust and moisture, which is useful for factory-floor placement. The specified color is red and the stack is three layers, so it is more compact than the four- or five-tier options. At USD 41.95, it is about USD 10 more than the 110VAC three-color tower, making it a reasonable DC-friendly middle choice.
Industrial Signal Tower Light - 110VAC 3-Color LED Stack Flashing Warning Light
The lowest listed price in this set, USD 31.56, belongs to this 110VAC tower. It combines a built-in buzzer with a three-color LED stack and is described as suitable for displaying operating status on machine tools, special machines, and robots. The description also says the round tower design gives 360-degree visibility and includes flashing light modes. If you have a 110V AC outlet or a machine-side control circuit at that voltage, this is the most economical way to get a visual plus audible signal. The limitation is its scope: it is a compact three-color unit, so it cannot show as many distinct statuses as the five-tier USB model, and it does not run on low-voltage DC.
Final recommendation by use case
Choose the 5-Stack USB LED Andon Tower Signal Light when USB power is already at the workstation and your status map needs more than the basic color set.
Choose the ANDONT Industrial 4 Stack when you prefer an aluminum pole and want a mid-priced four-stack signal.
Choose the Signal Tower 3-Layer Buzzer when your control circuit is 12V/24V DC and you want a buzzer plus steady or flashing modes.
Choose the Industrial Signal Tower Light 110VAC when you want the lowest listed price and your machine is on 110V AC.
