Tail light turns on then off. So does replacement taillight.

Here's a new one, didn't find it in any existing threads.
2014 P85, drivers outer tail light attached to charge port, NOT the trunk lid lights.
I click Parking lights on MCU, watch lights turn on at speedometer and rear, then 2 seconds after, the driver's tail light turns back off. Brake lights and turn signals working fine, tail light is only problem.

Interesting part is I just bought and plugged in an already tested good replacement taillight, and still doing exact same thing on my car.

After the 2 seconds, while sitting in the driver's seat, I can hear a quiet whoosh sound, like an eagle's cry, duration less than 1 second, and it stops at the exact instant the driver's tail light turns off. I tried to record the sound but it seems it was too quiet for my phone to pick up.
