Strange noise / whining from left speaker (intermittent)

Hello! Just picked up a '02 C4S this weekend and I have some fairly minor issues with it. This one is a bit weird and I've only been able to find one other post on this board about it in the TT section () but with no sollution found.

I occationally get an intermittent whine from my left, front speaker. It will follow the alternator, but it's not depending on the alternator to be there. As in, it will not go away by simply killing the engine.

However, turning off and on the litronics will kill it. Simply turning off the lights does not help, it's there until they fire back up.

I made this youtube video of it:

Has anyone seen this before ? I find it fairly odd and don't really have that many great ideas to what it can be. Perhaps a bad grounding on one of the litronics ballasts that somehow recharges and dissipates when the lights are turned on again ?
