After installing my Reverse Glow/White Face Gauges, I noticed that whenever I start my car this dinging sound starts up for a few seconds stops for a few seconds and repeats 4 - 5 times then stops. I assume that this is the seatbelt warning but it never used to do this prior to my gauge install.

I also noticed that the whenever I open my door it dings once! Maybe it did it before and I just didn't notice the ding when the door opens but it's kind of weird!

Is this normal?
