My "new-to-me" 2004 XJ8 had a left low beam aimed too low, so I was able to bring it up with the appropriate allen wrench. But in doing so, the left high beam is shooting up too high. The adjuster next to it has a different cap on it, unlike the allen for the low beam. Can anyone tell me how that works?

 

have a look at this this might be helpful, i did some research for you
