Adjust headlights.

Hi All,
Can someone provide guidelines how to adjust headlights? Need to get them down a little.
I remember reading some posts here and it was stated there is a small hole for screwdriver.
Cant find anything.
Please help.

Found it within 3 seconds. Above the drivers side headlamp, close to the warning sticker about the 25000 volt shock danger, there's a hole in the rad support. If you shine a flashlight down that hole, you should see a whitish Allen (hex) bolt head. I'm guessing that with a +/- 12" 1/4" extension or two and an Allen head bit you should be able to adjust it easily enough

Yep. Its there, vertical adjustment.
Its better to use Torx T-40 fits right in and much easy to use.
Were is horizontal screw?

I checked and....uhhhhh, no idea whatsoever...

And it's weird that a Torx fits better. Just checked again and I swear that's an Allen head screw

Yes it is, there is a hole right in the middle, and I believe its actually designed for it. ))

You talking about the vertical screw, or horizontal?
