Xenon Bulb Replacement Question

[Bill Valley]

Most knowledgeable and friendly fellow Xoutposters, I have an issue with my Xenon bulbs. I replaced the bulbs about a month ago. Prior to replacing, the driver's side beam was significantly lower than the passenger side. I figure this is to avoid blinding the cars travelling the other direction. Since replacing, the beams are at the same level. I had assumed the auto leveling would adjust, but it has not. Is there a trick to the driver's side install? I did the passenger side first which sat flush in the housing, but I think the driver's side bulb was installed at a slight angle. I say think because I could not get a good look at the bulb during the install. Is the bulb supposed to sit at an angle in the housing?

Thanks!
