Stack Lights, Industrial Signal Tower with Rotatable Base, Steady/Flashing Light Switchable, 12V/24V DC (3-Layer, No Buzzer)

Good size, looks good and worked fine -- Easy to set up but hole must be under the base to route the wire.

Bought this for a classroom project and it works pretty well. The lights are bright, but not bright enough to use outside in full sun and be reliable. Little switch on the PCB board to switch between flashing and solid, each color is independent. Both colors can be used at the same time. It's not really industrial grade, but it's also not at that price point. A similar light for a factory machine was over 500 dollars.

Works fine.

I have a 240 volt air compressor connected through a disconnect and plugged into an L60-30R. After forgetting one day to shut the disconnect off, I got mad at myself since it’s never a good idea to leave a compressor energized while you’re not around in case a hose blows. Big fire hazard. So I added this light and after opening it up to get to the switch to make it flash, I’m happy with it. Just note, it’s not very bright. It’s also cheaply made, and switching modes requires more fiddling around than it should, which is why I deducted a star. I hope it lasts.

I’m using this in my garage with a 12vdc power brick I had laying around. Got to use my soldering skills after many years to connect it up. I have the brick plugged into a smart plug, controlled by Home Assistant. I use this to light up the lamp when the home security system is armed. So family members coming in thru the garage at night get a visual indication of the state of the security system. Light is bright and has options for steady or flashing. Very well made and fit my use case perfectly.

It is difficult to see the lamps in daylight. They are ok in the dark.

Works as well as ones costing five times as much.

This is very easy to see from all angles. Build quality seems good. It is all plastic, so mount it where it won't get bumped and should last a long time. It has 4 wires, 1 for ground and 1 for each color.
