3 Colors Single Layer Three Stack Light, 60MM, Industrial Warning Lights, IP67(24VDC, Waterproof, Red/Yellow/Green, with Buzzer)

EZ to install.

Interesting little light but not as usable in my Light EV applications as almost every Light EV has moved on from 24VDC to 36V, 48V, or 52V. Not worth putting in place a DC to DC converter to make this and other 12 or 24V accessories usable.

While the wiring diagram seems to be universal for a line of products - showing 7 wires with 6 possible outputs whereas this version only has 5 wires for 4 outputs all sharing 1 diffuser. The wiring instructions cover all the bases for the design if you know some of the basics of reading schematics with transistors. A nice little extra perk is that the wiring diagram included with the lights has a tacky backing strip - think strong sticky note - that you can tag the wire and avoid losing the diagram in the future.In terms of actual setup I particularly like that as long as you are properly connecting the "common" black wire to your power source, you don't need to worry too much about reverse polarity problems as the signal lines are set up to power PNP or NPN transistors to control the lights/buzzer. This worked just fine with the common cathode (-) or common anode (+) wiring. I don't think any single signal drew more than .02A draw but expect some variation - some were barely .01A when powered up. These aren't 1W lights, so don't expect super bright but any given color was clearly visible in my well-lit workspace.The biggest downside is the relatively high voltage needed. A lot of the electronics I've been working with tend to use a 12v signal or less, so while 24v isn't out of reach, you need to think about your power supplies if you're using Arduinos/Raspberry Pis or other variants of MCUs and single board computers. There are activation voltages between ~10V to ~15V depending on what color and lights you are trying to turn on (shown with the faded red image)- and while you don't have a lot of control over the intensity of light (although maybe able to do some with PWM pins on an Arduino or similar MCU) you can have all the signals of the light powered in parallel giving you some control of the mixed colors. You probably won't get full RGB lights but certainly are some options to work with.Overall seems designed for industrial or commercial use but I could see this working in a maker space or personal shop when you want some safety features for CNC equipment or other tool safety awareness

Sadly, no color of any of the lights work at all. The buzzer does work, but it's pretty quiet and high pitched anyway. The unit is pretty small, and somehow the sticker that comes on it showing what each wire color does is completely inaccurate, showing colors that don't even exist and more wires than it has. Do wish the LEDs worked though, as I do have a different use for this than I originally intended had they, given how water resistant it seems.

There is no documentation in the box, the wiring label is not accurate (there is no blue or white wire in my cable). The buzzer is very quiet. The entire unit is extremely small so I can't use it where I originally intended. The colors are nice but muted, not what I would expect for an emergency lamp beacon. This is just not at all what I was expecting.

I tried to take some pictures with the beacon on, but the camera washed out the colors. What the vendor shows, soft colors, is pretty accurate. Nice weight, looks like decent quality plastic.The buzzer is more of a high pitch squeak then a low buz. That's ok with me, just that you know.I headlined this as commercial. There is no documentation in the box, the wiring label on the cabel is cute, but not accurate (there is no blue or white wire in my cable, and the attached label is croocked and wrinkly. No input current listed, no indoor/outdoor rating included, etc. Lacking details that would make this a decent beacon in an arcade more so then in a chemical plant.

I am presently working on building another CNC router for my hobby use. I wanted to add some visual indication that the machine is running, finished, or needs attention such as for a bit change. I saw this available in the Vine program and ordered one to try out.There were no instructions included. However, I previously picked up this same company’s tower light and the wiring is the same. Black for either ground or source power, red for red, green (almost black) for green, yellow/orange for yellow, and peach/pink for buzzer.I tested it out with a 24V power supply, first connecting the black wire to negative and then testing each of the other wires individually, all lights worked fine and the buzzer is loud at the 18” or so I was from it. I then connected black to positive and again all worked fine. The only slight negative that I have is that the green light wire is very dark green, nearly black, so some may have a bit of difficulty distinguishing between the two, but a quick power test between one of the other wires and the two dark ones will tell you which is which.I haven’t decided if I’ll use this or the tower lights for my CNC build; however, I also have a couple other machines that are candidates for a light system.

If you need the equivalent of an emergency tower light, but your space is limited, this unit is PERFECT.Be aware that it NEEDS a full 24 VDC in order to be at its full brightness. I tried it on 12 volts and it was just too dim, but at 24 it definitely gets your attention!I'm planning to use this with a Raspberry Pi as a Silence Sensor alert (at a radio station). The DJ will know immediately if they're off the air.Also -- it might not be obvious in the description, but the unit includes a buzzer. One thing would make this even more useful, and that would be a shutter over the buzzer port, to allow for some volume adjustment.
