I odered this item first 2 years ago, as an extra pair of lights on my motorcycle. 4000km's later, one of the two lights starts to blink. Not a big deal, because it has a connector. So i ordered a new pair of this lamps. When i tried to change the lights, one has no thread in it's mounting holes. And the other light came with a wrong polarity in its connector. so both are useless, unless i change my wiring and redrill the holes.
