Kycola Wii Sensor Bar NA06 USB Wired Wii Sensor Durable Replacement For Nintendo Wii/Wii U/PC-Black

Cable is really delicate but gets the job done

This sensor bar is working well, compatible with nintendo Wii and Wi U console, and it is very easy to use. the sensor bar features infrered ray inside it, each side of sensor bar have three infrared light, but I can't see those light with my naked eyes, so if anyone could tell me how to see those infrared light, and it is also very important for all of us to check if the sensor bar is working or not. This sensor bar is working great now I can feel it is working, but I still want to know how to check. Thanks.
