On the US JK, there is only one adjuster for each headlight, and it can only be adjusted up and down, but not side to side. You will need to install each euro headlight adjuster screw in your JK headlight bucket, which screws in and out and properly adjusts the light to make it easier to make the necessary horizontal adjustments! All you need to do is replace the second screw with one of these and you can now adjust left/right to make sure you don't block oncoming traffic!
