Whelen LR11 have 1 black, 1 white wire. Which is pos/neg?

Second Q, on my lightbar I am doing the 911ep LR11 swap for the halogen MR11. They're just 2 white wires. Anyone know with the plug clip facing up (so as you look at circuit board clipping in), which is pos/neg? Assuming left is pos?

Other: just try it, almost everything is protected against reverse polarity these days, the probability of you fryin it is slim
