How To Open L&M ARC HID?
 

I had the battery in my coat & stepped a bit to far from the bike where the light was mounted. Seem to have pulled on the cord enough that it loses contact with the light. If I push it back it'll turn on. Does anyone have any idea how to get to the insides?

Two things:

L&M repaired my long out of warranty HID for this same issue for the cost of shipping it to them. They even did a full test of the battery and the whole unit, essentially refurbishing it. FREE. So contact them (or have your LBS do it).

Failing that, the front lens bezel will rotate to about the two O'clock position to click off the lens and provide access. Do not touch or contaminate the lens or bulb in any way.

Contact them first, though.
