I picked up an LED MR-16 bulb on eBay. 2 watt, 48 LEDs, 12 volt DC. When it came I saw that they'd neglected to mark which pin was positive and which negative. Turns out it makes no difference, it lights either way. All the LEDs. The bulb is too well sealed to open without destroying it. Can anyone explain how they came up with an unpolarized LED bulb??
