2009 C300 Sport with approximately 65,000 miles.

The car is experiencing two very odd lighting issues that I'm hoping someone can please help me diagnose.

The first issue is some of the dash lights blink off and on while the car is on. Particularly the ring around the speedometer and the "lights on" indicator. I've made a 20 second video showing the problem here.

Sometimes while in Automatic "A" lighting mode, the dash lights will stay on / off for longer periods of time. Instead of blinking like they do in the video above.

This doesnt seem to happen when the light mode is set to "off" (O).

The second issue is about half of the time when I shut the car off, remove the key, and leave the lights set to "off mode" (O), just the passenger's side of the car's eyelid and taillight lights stay on.

Let me know if I can provide any additional information. I am definitely not a car guy, so I'm sure my post is missing important details.

Thanks in advance.
