Baomain LED Indicator Light Energy Saving Pilot Signal Lamp AD16-22D/S31 24V AC/DC 20mAGreen Yellow Red Blue White 5 Pcs

These aren't super bright but I just wanted these for a PLC test box so as long as you can see them inside in a lit room I couldn't care. The plastic parts are decent quality and having a finger ring for holding them in the panel and screw down terminals they are very easy to fit with no soldering required. Very pleased with these and would recommend them.

I purchased these to wire into an HVAC panel so the end-user could have a visual for when the various components in their system were receiving power (Fan, compressor, heating unit...). Excellent price and no issues so far after being in service for several months.

Purchased these for use in the PLC trainer I built. They're bright enough and the price was good. Only complaint is the screw terminals were a little difficult to tighten down on a couple of them, but for the intended purpose, I'm happy with them.

Works as expected

I like these, but the connections inside to the terminals are poorly designed and executed. I had to resolder cold and open solder joints.

This is exactly what I wanted.. It worked perfectly for my Annunciator panel I made for our heating and cooling system.

Standard, reliable, easy to install.

Excellent for indoor use and a bargain with good quality. Not super bright but good color and sufficient for indicator applications. A couple of issues using them outdoors. The most important one is that the plastic lens cover fades in outdoor light (UV) to the point that it may be difficult to tell whether they are on or not. The actual leds and circuitry is sealed although I have had one burn out outside. They also may not be bright enough for outdoor use. As an aside, they use 500 ohm resistors on the positive and negative connections so eliminating these resistors would likely allow them to run on lower voltages, like 12 volts. The also will run on DC or AC.
