Headlight aim weirdness - I'm stumped!

Just got back from a week's worth of riding up Sacramento way, including a ride out to Nevada with the crew.

Here's the dealio. I'm usually fairly precise about things, including aiming my headlight. When I last aimed it some six months ago I had the bike fully loaded (as that's how I normally ride) and set the headlight up so that the beam dropped 2" in 25 feet. Pretty much by the book.

Sunday SLO-KLR told me my headlight was aimed too low. OK, maybe so, but I don't have my full load on. We'd been riding in the day, so what am I going to notice, eh?

We were on the way back home and I was on point when the sun went down. Next thing I know SLO's behind me. SLO has good lights. As usual, he was on top of things and figured I wouldn't be able to see a moose if it ran out in front of me, so he lit the way. (He's very handy to have around - constantly saving my ass.) With his lights behind me I really didn't notice how low my light was.

We stopped for a break and I moved to the middle of the pack for the tighter twisties because I have some night blindness and we all figured it would be be better for Blind Melon Chitlin to be in the middle of the pack with tail lights to follow.

Holy Carp! Now I could tell how low it was and my dismissing it as being caused by not having 40 pounds of stuff on the back was way off the mark. Speaking of Mark, I was behind him at normal following distance and wasn't even lighting up his reflectors. There was just a mighty dark place out there.

This morning I checked it and it is aimed at about a foot off the ground at 25 feet. I disassembled the cowling and inspected the headlamp assembly, both inside and out. Nothing is broken, nothing is missing, nothing wiggles, the lamps were firmly in place. I can't find anything wrong except that it's pointed at the ground.

We were doing some riding over some sorta rough terrain (nothing really that rough, though), but I can't find anything that would have gotten knocked loose, unless the adjusting bolt somehow stripped the nylon nut that it runs through.

I'll be adjusting it tonight and keeping an eye on it over the course of the next few weeks.

Did you try swapping in a new bulb? Maybe something happened to the element in the bulb itself? That thing was really dim in my mirror.

If you lay on the ground 25 feet out it's really pretty bright.

That's one thing I didn't think of, that the bulb itself got whacked. I'll try that.

Damn, gotta take the cowl off again....

Could the vibrations of the road have caused the adjuster to reposition the light? Can you adjust it down anymore? Maybe toss some locktite in there when you reposition it...

I think if the Gen2 adjuster would go out of whack from vibes we'd have heard about it by now. There are lots of people who have put more miles on one than I have.

The adjuster seems to still need a bit of torque to get it to turn, too.

Not to be a smart-ass, but didn't the Beatles write good vibration?

Okay, I feel better. Not smarter, just redeemed.

I think that one was written by Brian Wilson, of the Beach Boys.

And weren't they the "Beetles", like the car?

"Lighten up on yourself," Tom said brightly...

Darin is ****ing handy isn't he? I was gonna suggest swapping out the bulbs, too. I don't know man. That's weird. As I am stuck in bed, I will do a bit of research and let you know if anything comes up.
