Wow, looks like I've created quite a storm. But I've got a partial answer I think from my fellow Texan. This sensor that's triggered whenever the automatic lamp determines that its dark outside, is there a way to prevent it from triggering the lamp defective indicator? I agree that disabling the function altogether isn't a good idea.
Additionally, is there a particular power source that controls the bright light switch that isn't being powered by the automatic lamp sensor?
Finally, is there a diagram that explains the MB W210 headlamp system? If so I could print it out and hand it to my tech?
