Okay, I don’t know what I did, but my passenger side headlight is now aiming … up (and to the right). I pulled it all apart again tonight and I’m pretty sure I failed to put the retaining clip back in place properly, but when I attempted to look it up in my owner’s manual …
… I realized I’m missing my owner’s manual.
On the other hand — I’ve got headlights. Who cares if only one of them is actually illuminating the direction I’m going in?
