The driver side highlight flashes randomly, it can happen while car is on or off.
The frequency is inconsistent it happens very randomly.
I've attached a short video.

I don't see the video. If you are on mobile it can take some time to upload. Anyway, it sounds like the BCM is going out. To be sure we perform a CAN scan to confirm the failure. Here is a guide and video on how to do the job and I have included how to change out the BCM and the headlight wiring diagram so you can see how the system works in the diagrams below.
