Separate High/Low Beam Headlight Adj???
I can't find anything that allows for a separate adjustment of high and low beams. The problem that I have is that the low beams are fine, but the high beams shine about 20ft up off the pavement at about 50 feet ( I can see the beam in the trees on the side of the road).
The bulbs seem seated OK, but ??????? Any ideas?????

The lamps are boresighted by the position in the headlamp housing. Adjust high and you adjust low in sympathyI'd say it has to be something to do with how the individual lamps are seated in the housing. A tweak should fix it.

I didn't look that close at the time. I could have missed that real easy. Will check in the morning... Seems like a logical answer...

I remember someone else about a year ago posting a thread with this exact same problem. I can't remember if the cause or solution was ever identified. Seems like I remember them using the phrase "spotlighting in the trees" or something like that. You might try doing a search here on the forum to see if you can find that other thread.

When I added aftermarket HID bulbs, I had to adjust the housing up for the new low beams. Now the high beams are "tree spotlighters", but I really don't need high beams with the low beam HIDs. I was careful not to aim the HIDs too high, so I very rarely get anybody blinking their highs when they are coming toward me.

I'm afraid that if I adjusted the high beams properly that the low beam would be aimed about 10 ft in front of my Vette (probably an exaggeration), but they would not be where they should be. They would be aimed very low.
