Before we purchased, wife noticed headlight out, which previous owner replaced himself. We don't drive much at night, so did not notice bad aiming or that one headlight installed upside down. Pretty sure I can re-install headlight right side up. But, not sure how to aim. Have heard something about 26 feet away from wall and adjust light so many inches from pavement. Search on tech notes did not provide answer. Know fsm probably has answer, but have not purchased yet. Anyone know how to aim headlights vertically and horizontally and difference between left and right??

Also, it's been a while since I replaced a headlight but if I remember correctly, you'd really have to work at installing one upside down. I thought it was pretty much idiot-proof. Well, at least John-proof...
While it's possible that somebody did not install a headlamp correctly, it would be hard to do. The headlamp housing has notches in it that match up with molded-in tabs on the headlamp. Any lettering or names on the lense will have to be right-side up (readable) to make sure the lamp is installed correctly.
If the lamp is not placed in the housing correctly, the metal ring that is used to hold the lamp in place will not tighten down properly.
Also, there is a small spring that holds the lamp housing to the frame of the bucket so that the adjustment screws will allow for movement. Check to make sure the spring is there. Also, it may be that one or both of the adjuster screws have fallen out of their notches on the headlamp housing. That would allow the housing to move around.
I have learned nothing too hard for this previous owner. I couldn't believe when I lifted the hood and was able to read one headlight right side up and the other upside down.
Thanks a heep for the advice. Will tackle this weekend and hope the spring is there.

Believe it or not, the headlight can easily be put in upside down....well, as long as you cannot read the writing on the lamp. No notches in the housing or the retainer frame. Sorry, have to take back some of the "idiot" thinking of the previous owner. Well, not all, he did not understand that when the lights are flipped the headlight would read upside down. Anyway, easily turned lamp and re-installed the hardware. Springs still in place and have to, yet aim the light.
Have not contacted Sylvania, yet. But, assume the lamp upside down would not throw the high beam correctly, either up or to the right or left. You know anything about lamps?
