    Good quality and easy to use even it comes with no instractions. Uses 3 resistors one for every led.

    stiglo bez oštećenja nije još isprobano mada nebi ni trebalo da bude problema.

    The picture shows small crystal clear LEDs but the ones I received are larger cloudy LEDs. They cover most of the circles that you see around the LEDs in the picture. However, the LEDs that I received look more like real traffic lights so that is not a problem. In addition, the specifications say that these are 5v LEDs. However, I tested them with 3 volts and they were bright, so I suspect that 5 volts would destroy the LEDs. So I am using them with about a 90 ohm resistor in my Arduino project and they work great.

    Although each LED seems to have an SMD series resistor, the series resistor of the green LED has a value of 0 ohms! Without another resistor, the green LED on the Arduino can be destroyed. Without another resistor on the green LED, an Arduino can be destroyed. For a Raspberry Pi it may work without a resistor. The forward voltages of the LEDs are about 2V (red), 2,1V (yellow) and 3V (green).

    This tricolor block of fire is of very good quality. I installed it with my ARduino and it works fine. 1 resistance and it's gone and I'm going to set up a miniature circuit for my boy. Super functioning is perfect - Ce bloc de feu tricolore est de très bonne qualité. Je l'ai installé avec mon ARduino et cela fonctionne très bien. 1 résistance et hop c'est partie et je vais mettre en place sur un petit circuit miniature pour mon garçon. Super fonctionnement c'est parfait

    Very useful but different model scale is better to have, above all 1/160 , 1/120 and 1/87 for model train.

    LED's were not the clear type but diffused but otherwise happy with the units as they function just fine.
