2-Stack LED Andon Tower Signal Light with Buzzer, 16  ft

This is the kind of equipment where you can immediately tell whether it’s built for real-world use or just light-duty applications—and this setup leans much closer to true industrial-grade than most plug-and-play signal towers I’ve handled. The tower itself has a solid feel right out of the box. The lens housings are well-seated, the plastic isn’t brittle, and the stack assembly doesn’t have that loose, rattly feel you get from cheaper units. The red/green output is bright and highly visible even in well-lit environments, which is critical if you're using this in a shop, warehouse, or production setting. What I appreciated most is the control box setup. It simplifies integration quite a bit, especially if you’re not wiring directly into a PLC system. The on/off/flash functionality is straightforward and responsive, and the included Mean Well power adapter is a big plus—those are known for reliability, and it shows in stable performance with no flickering or inconsistencies. The buzzer is loud enough to get attention without being obnoxious. In a noisy environment, it cuts through just enough to be functional without becoming a constant irritation. The included extension cords (6 ft and 16 ft) are actually usable lengths, not throwaway add-ons. That makes placement more flexible without needing immediate modifications. Compared to lower-end signal towers, this feels like a more complete and dependable system. It’s not over-engineered, but it’s clearly designed for repeat use in environments where downtime or missed signals matter. Pros • Bright, highly visible LED indicators • Solid construction with stable assembly • Reliable Mean Well power supply included • Easy-to-use control box with responsive inputs • Practical cord lengths for flexible installation Cons • Limited to basic two-color signaling (no multi-state expansion) • Mounting hardware could be more robust depending on application Overall A dependable, well-built signaling solution that bridges the gap between basic plug-and-play units and full industrial systems. Ideal for small operations, workstations, or process alerts.

I picked up this 2-stack LED Andon tower signal light to use in a small workshop setup where I needed a clear visual (and audible) indicator for machine status, and it’s honestly been a really practical addition. Right out of the box, everything was packaged well and felt more solid than I expected. The components didn’t feel cheap or flimsy, and the included control box and power adapter made it clear this was designed to be plug-and-play without a complicated setup. I appreciated that it came with both a shorter and longer extension cord, which gave me flexibility when deciding where to mount it. Setup was straightforward. I mounted the light where it’s easily visible, connected the cables, and had it up and running pretty quickly without needing to look up extra instructions. The controls are simple to understand — switching between on, off, and flashing modes for each color didn’t take any trial and error. In actual use, the red and green lights are bright and very easy to see, even from across the room. The flashing mode is especially helpful for drawing attention when something needs immediate action. The buzzer is noticeable without being overwhelming — it’s loud enough to alert you, but not so loud that it becomes annoying during normal operation. I’ve been using it to signal when equipment is running versus when it needs attention, and it’s made things more efficient since I don’t have to constantly check on the machine. It would also work well in a garage, small production area, or even for hobby setups where visual alerts are helpful. One small thing to note is that while it’s simple to use, this is more of a basic control system — so if you’re looking for something highly programmable or integrated into automation software, this may not be the right fit. But for straightforward signaling, it does exactly what it’s supposed to do. Overall, this is a reliable, easy-to-use signal light system that delivers on its purpose. It’s bright, simple, and effective, especially if you want a no-fuss setup that works right out of the box.

I’ve been very impressed with this 2-stack LED Andon tower signal light setup. The build quality feels much better than I expected for the price, and everything arrived well packaged and ready to use. The included Mean Well industrial power adapter is a nice touch because it gives confidence that the system is using reliable components instead of a cheap generic adapter. Installation and setup were extremely quick. It’s basically plug-and-play as advertised, and I had it running within minutes. The light tower itself is lightweight, which made mounting and positioning very easy without needing heavy hardware or extra support. The included extension cord also adds flexibility for larger workspaces or equipment setups. Functionality is excellent. The red and green LEDs are bright and easy to see from a distance, and the different on, off, and flashing modes work exactly as intended. The buzzer is loud enough to grab attention in a busy environment without being painfully obnoxious. This makes it useful for workshops, production areas, testing stations, or even creative home automation projects. For the money, I think this offers very solid value. You get a complete setup with the control box, power supply, and extension cable included, which saves the hassle of sourcing compatible parts separately. My only real complaint is the control box layout. There are extra buttons that appear like they should have functions, but they don’t actually do anything in this configuration. That was confusing at first and made the controls feel less intuitive than they could be. A simpler control layout or better labeling would improve the user experience quite a bit. Aside from that minor issue, this is a great quality signal tower kit that works reliably, installs fast, and performs exactly as needed.

Regardless of how many lights you need, ANDONT provides the same 6-button control box for this particular series of stack lights (this series doesn't come with industrial 2-position selector switches). Like the "data sheet" on this product page shows, whether each signal will flash or not (and how the buzzer will be customized) has to be configured using DIP switches in the base of the light stack--the 6-button control box itself cannot control the flashing of the lights. This product series is designed to be be manually operated. Even though the control box and the stack lights operate on the 24VDC industrial standard, there is no way to externally interface with this device and automate the control of the lights or the buzzer. And while individual LED modules can be swapped, the ANDONT store doesn't offer replacements for individual LED units. The most appropriate use of this model is basically the equivalent of a storefront's "We're open" sign.

I bought the 2-Stack LED Andon Tower Signal Light with Buzzer for my home setup, which is a polite way of saying “my desk where absolutely nothing is manufactured, monitored, or mission-critical.” Out of the box, it looks like it should be installed next to a machine that costs more than my entire life trajectory. Instead, I plugged it into my extension cord like a man trying to summon industrial authority over a pile of laundry and unresolved emails. The setup was plug-and-play, which is good, because if it required actual industrial knowledge I would currently be living in silence and shame. Within minutes, I had a full red/green alert system proudly standing on my desk like my life had suddenly become a factory floor—despite the only “production” happening being my existential dread. Now, every time I turn it on, I feel like I’m managing something extremely important. The buzzer is the real star. Nothing quite prepares you for the sound of industrial urgency echoing through a room where the most dangerous equipment is a slightly overfilled coffee mug. My cat now reacts like we are one missed step away from a facility-wide evacuation. The extension cords are long enough that I briefly considered setting up a fake control room in different parts of my apartment, but then I remembered I do not, in fact, control anything except brightness settings on my monitor.

This two-stack Andon light is a professional solution for signaling status changes in a warehouse, shop, or office. It features a bright red and green LED tower paired with a loud buzzer and a dedicated control box that’s easy to operate. The kit is genuinely "plug-and-play," including a high-quality Mean Well power adapter and plenty of extension cord length to get it mounted exactly where it’s visible. It offers solid, flash, or off modes, providing a clear visual cue that helps keep production moving or signals when assistance is needed. The LEDs are incredibly bright and visible from across a large room, even under harsh industrial lighting. The buzzer has a good volume to it—loud enough to be heard over background noise but not so piercing that it’s painful. Having the control box pre-wired saves a ton of time on installation; you basically just mount the tower and plug it in. The build quality of the switches feels industrial and ready for heavy daily use, making it a reliable tool for improving workflow communication.

I didn’t realize how useful this would be until I set it up. I actually got it to mess around with in my garage, but now I’m using it as a “don’t ignore me” alert system. The wiring is pretty straightforward — plug-and-play like they say. The control box makes it easy to switch between colors and modes without guessing what does what. The buzzer is no joke. My neighbor heard it the first time I tested it and came over thinking something was wrong. So yeah… it definitely gets attention. The lights are bright even during the day, and the red/green combo is super clear. I’ve been using green for “good to go” and red when something needs attention — simple but effective. Feels solid overall, not flimsy. The long cable helps too so you’re not stuck mounting it right next to the outlet. If you need something that actually grabs attention (shop, garage, or even just messing around like me), this thing delivers.
