Left HID randomly flickers off/on when turning left

Having tried all the obvious fixes, control unit, bulb swaps, tail light ground, shaking harness... I continue to have my left HID randomly go out or flicker on left turns. My guess is there is something not-so-obvious that is loose, hoping someone has experienced the same and isolated it Any advice appreciated.

Check the wiring inside the headlight, under the access cap. The wires are known to deteriorate and break, hard to see at first. I soldered mine and covered with liquid electrical tape. Check near the zip ties, that's where mine were broken.

Thanks will check that out!
