I have factory xenons on my 996 and one side burns hotter than the other. is there a way to adjust this?

 

I don't think so. xenon supposed to burn cool unlike halogen. do they look the same color and brightness?

 

when i turn on the lights they both look the same but after 30sec or so one side stays blue and the other gets (less blue, yellowish kinda)

 

I wonder if that's a sign of bulb wearing out? The light is emitted due to gas reacting to electrical charges I believe. So, either something is wrong with the gas inside (leaking) or the ballast (not providing enough charge). Check eBay once in a while. If you come across a new one for cheap, I'd get it and swap it.
