The Red-green-yellow-blue-white-indicator-lights are essential for industrial safety:

An AD16-signal-lamp-screw-terminal is a crucial component in industrial automation. Unlike pin-type indicators, the plastic-LED-indicator-light-with-screw-foot allows for faster field wiring without specialized tools or soldering. It serves as a visual feedback mechanism, alerting operators to machine status, power availability, or potential hazards. Its PA66 nylon construction provides superior chemical resistance and electrical insulation, making it the preferred choice for distribution boxes and CNC cabinets where space and reliability are paramount.

They are cheap indicators for projects, seem well enough made. One of the boxes arrived open and all 20 indicators out of the 2 packages were super scratched up and dirty. Haven't tested them yet for functionality.
I needed an on an off indicator for my water level controller. These lights fit the bill perfectly. Lights are a little dim for direct sunlight however a little shade or night operations allows easy read. Installation has been running for over three months now and they continue to work perfectly.
They come with the terminals very snug (think car wheel lugs after an impact wrench got to em) but if you crank down on them too hard the terminals can break off in their housing. If you don't break them setting them up then they can work quite well. They aren't meant to be used as room lights or flash light but they will be fairly visible when lit up. They seem very easy to break during the set up process, though. The ones that come with wires attached don't need the same amount of elbow grease to set them up so they might be a better option
We have used FILN indicators for years in our automation systems. Consistent performance and the screw terminals are very convenient.
Great
Used 10 pcs for a local electrical upgrade. Solid performance so far. Will order again.
ok
산업용 패널에 잘 맞네요. 나사식 단자라 배선이 매우 편리합니다.
Eingesetzt in unsere Schaltschränke. Die Schraubanschlüsse sind sehr praktisch. Zuverlässig.
Ordered 50 units for our control panels. The screw terminal design is a huge time-saver compared to soldering. Very solid fit. (´• ω •`)
Bought 25 pcs for my DIY machine rebuild. Easy to wire, bright, and durable plastic housing. Will definitely be a repeat customer.
This product is very good quality I recommend this for your project
Works pretty well!
