I believe there is fluid in the back part of the resevoir. I have also thought about unplugging the sensor wires and testing for continuity on the resevoir pins. I also wondered if unplugging might reset something but probably not as this is pretty basic system and not a new computerized gizmo. I don't think it is likely to be the parking brake as that part has worked flawlessly for the past 3 summers. I am assuming it is just the float sticking or the contacts not being clean. The cd manual says the sensor is not removable so I guess that I may have to probe inside with a piece of wire to see if I can make the float move. There is a rubber cap over the sensor float rod and I assume it just pries off. I was a bit leery of doing so for fear that it might then need the shoegoo treatment. I wondered if that part was available if needed. I like to avoid messing with old rubber parts like that.
Will start trying some things. So far, I have mostly just looked at it and thought about it which has been alright because the brakes work fine and I know it is just the sensor contacts acting up.

Also, can you see fluid on the rear chamber of the reservoir? It can be difficult to fill the rear sometimes, you have to overflow the front side into the rear, although I don't think that particular one is really bad. Try unplugging the sensor wires -- if the light goes out, the switch it stuck, the float is sunk, or, as in my brother's 300D, it fell off the pin and is not floating beside it! You will have to remove the cap that holds the sensor in, and I don't remember if it pries off or screws off. And don't forget that the parking brake uses the same lamp. Pedal might not be all the way up.
