I don't THINK there is anything in between those 4.5 minutes (I checked the 30/60 second intervals). I left a video running for 20 minutes and noted there was a flicker at every 4.5 minute interval.

In reading some older E90 threads, I'm thinking this is the check the system does to see if the bulb is burnt out. Since LEDs light up instantly vs incandescents (which wouldn't even light to a significant amount on that pulse), we get the flicker.

I guess I'll do some more looking in the coding section, and/or figure out what else to do. I guess a flicker every 5 minutes is not that bad, although at night it is somewhat visible.
