This is the LED I have
https://www.jameco.com/webapp/wcs/s...Id=10001&ddkey=http:StoreCatalogDrillDownView
It has 4 Pins and they told me the corner with the Notch is the + Pin and all the other Pins are the - Pins.
But when I put my Black wire to the Notch Pin and the Red wire to the other Pins it wont Lite.
But if I put the Black to any other Pin but the Notch and the Red to any other Pins it does Lite.
So what is the Notch corner for?
