Do you happen to know if your cruise control is working? And how did all this start the sequence of the lights?
The reason I asked about the cruise control is you have a Vehicle speed sensor that would affect your speedometer and cruise control. The first thing I would do is disconnect your battery for about 30 mins to see if this corrects the problem, inspect your battery terminals make sure they are free of corrosion. If you still have an issue I would have your battery and alternator checked out. The correct test an a battery is a Load test. Place's like auto zone can check this for you at no charge. They will also test your alternator out. My feelings are you are having a low voltage issue or an issue with your cars computer. If the battery and alternator are good I would think it is an issue with the cars computer.
