BTW, here's how you're suposed to line up the headlights. I'm sure everyone already knows this but I'll repeat it for good measure.
Find a wall next to a level paved area. Bring tape and a tape measure and go there at night.
Measure 25' (8.3m) back from the wall, and mark that point with tape. Line up the car on the tape, then pull the 25' forward until the car is about touching the wall, and turn off the headlights.
Put a piece of tape on the wall directly in front of the center of the Volvo emblem. For you cool kids running mesh grills, guestimate where the center of the car is. We'll call this point "V"
Put a square piece of tape directly in front of each projector lens. That is, when looking at the top and front the side the piece of tape should be lined up with the bulb. These two pieces are called "C"
Pull the car straight back until the nose is sitting at the 25' mark. Turn back on the headlights (so you can see, remember it's nighttime ) and walk back to the wall. It's time for some artwork:
Connect the both "C" dots with a horizontal line "H." Then extend the dots for "V" and the two "C"s straight down as shown. Next, measure from the "H" line down 3" or 76mm and add another horizontal line parallel to "H"
Now, using the two screws (shown above) on each side, make the pattern look like this:
You actually want to aim them a bit to the left (~1") of the vertical lines through "C" to get a better throw on the road. This will put the "kink" on the double yellow, instead of in the center of your lane. Don't go too crazy or you'll start blinding people.
The goal is a 3" drop at 25', equal height on both sides. Remember to take the tape off when you're done.
