I had a MR16 fixture led light that failed. I busted apart the glass casing to determine its failure. Besides the leds the light contained a resistor and a bridge rectifier IC. The rectifiers allow the light fixture to be powered reverse polarity and still work. In my case the resistor was poorly soldered and it came loose. After soldering the resistor back in, the leds worked again.

FWIW, the $5 panels in the OP do not work in reverse polarity.
