I did a search on the subject and came up with some info the Timcatz wrote. However, I'm not seeing this "white" cover on the headlight cover.
Can someone please tell me where the adjuster is on the Evo 8 headlights? It's really tight in the back of the unit...is that where the adjuster is located? Any info is greatly appreciated.

 

In one of the two main threads that Timzcat has info, I posted pictures of the adjusters, check your search again.
