I tested each and every one of these with a 12V power supply. Every one works and is the correct color (there are 5 bags of 10, each bag marked with the LED color). To the one-star reviewers who complained that not a single one lit up when tested with a 1.5V AA battery.... all I can say is "it's better to keep quiet and be thought a fool, than to open one's mouth and remove all doubt". Your LEDs were probably perfectly fine, as mine are - but you didn't provide enough voltage to light them up. LEDs are nonlinear devices and the closer the blue you get the higher the voltage needed to wake them up. A red or yellow LED might glow faintly with a 1.5V battery (you'll have to turn off the room lights to see), but green, blue or white (which is similar to blue electronically) won't do a thing at that low voltage. You're better off testing with a 3V coin cell, or better yet a 12V source (which is what these are designed for). So don't be swayed by the one-star reviewers who don't know what they're talking about. These LEDs work fine.

These were perfect for my 3d printed project! This was my first attempt at adding lights to anything. They were small and easy to fit in cramped places and had enough wire for me to work with. Easy to install and way cheaper than I thought I was going to have to pay for lights. I use the white lights for this project. The other side has a push switch that turns them on and off. And, I have lights left over for the next things I want to do!

Super bright

The lights are easy to wire into your project. I used these for my model railroad control panel and they work great! I bought more to use on other areas of my layout.

Decent size bulb and usable length of wire. Now super bright by any means but worked for what I needed then for. I paired mine with a coin style battery pack.

Great little LEDs for model building. 5 colors - Red, Green, Blue, Yellow and White (clear). I'm using as the lights on the bottom of a flying saucer model.

Bright LEDs with a great variety of colors. Appreciate that the diodes are already heat shrunk in line with the LED. Holders were tough to fit into the plastic project box I had but I think that was more the hole on the box was the incorrect size. Overall great value for high quality LEDs

These are perfect replacement for a car alarm LED. They look better than the original and are easy to put in. The thickness of the bezel around the steering wheel was a little too much. However, I did insert the mount for the LED from the front and then just place enough tension with the wires in the back to hold it in. No issues that I could see at this time.

easy to use , no need for a resistor

Me encanta el modelismo y es lo adecuado para mi. Funcionan al 💯👍
