You can see a picture of how I mounted the lights below. I took the picture yesterday. I got the lights last December and had ~800 miles, much commuting in cold NYC weather, predominately on the road, before the light failed. As I understand it from John, the failure was related to the HIDs I previoiusly installed, rather than cold weather or hard riding. I do not understand the mechanics of the interference btwn HIDs and LEDs and am hoping this will not repeat. I can tell you that HID/LED combo is stunningly brilliant. Here's the pic:
