You area Full Member, you have access to technical manual where in the section Electric System, Dashboard instruments it is described which light is which.
Bottom blue - high beam
Middle orange ( or red I suppose) - door open or brake fluid low
Top red - charging
Middle one will be lit without ignition when you open drivers door or any door, depending if you have switches in drivers only or both doors.
Middle one will be lit when brake fluid is low or when you bridge the pins in the master cylinder sockets but only with ignition on.
When you open door with ignition off and you have low brake fluid level or you bridge or short the pins in the master cylinder socket(s), your charging light will come on even without the key, fuel pump will start, etc. - you will power up the car as if she were with ignition on. This is a design issue of these cars.
Parking brake has no light whatsoever.
If you bridge the pins in the master cylinder socket without ignition, no light will switch on.
If you disconnect the blue wire from alternator, charging light will not be lit.
Assuming you have enough brake fluid and there is no short in that circuit, the normal operation is like this:
1. Doors closed, key out - nothing is lit.
2. Open door, key out - the middle light is lit
3. Close the door, nothing is lit
5. Key in, doors closed - still nothing lit
6. Key turned, doors closed - top red light is lit, you hear the fuel pump
8. Start the car, engine running, doors closed - top red light goes off, nothing is lit
9. Open door while engine is running - middle one lights up
10. Close door - it goes off
11. You are driving along, but you lost brake fluid - the middle light goes on, but when you turn off the engine, it goes off. Then when you open door to see what the hell happened, it will go on.
12. Probably the most important one: when you turn the key and hear the fuel pump, but the top light is off - you have no charging (can be burnt bulb or other failure in charging system).
And
When driving and the top light goes on - you just lost charging.
