Yes, welcome back Lance, glad you found us again, although we did try awfully hard not to let anyone know where we had gone
A strange and similar thing happened to me before Xmas, not the adjuster falling off, the silly cow thing, only it was a bull.
I was rattling along the M4, on a freezing cold Sunday afternoon, homeward bound from a very jolly biker's Xmas party.
Most cars, stuck in the 50-60 mph car park were drifting toward lane 2 or the Armco in a very definite attempt to let me squeeze by and I was very kindly taking up their offer and making progress.
Eventually the motorway cleared, all apart from the solid line of cars still stuck in lane 3 all trying to overtake the car in front.
Suddenly, the car I had found myslef behind stamped on his brakes so I lifted off and eased into the empty lane 2 but he pulled over as well and started shaking his fist in his mirror. Lane 1 and he follows suit, still shaking his fist. When I pulled out and moved tentatively alongside him, he wound his window down and started spluttering about me flashing my headlight on and off the whole time I was behind him, demanding to know why.
Now, I have always found it a trifle useless to flash the driver in front unless they are asleep and the only vehicle in the outside lane when a quick one normally wakes them up and moves them over and I certainly wasn't flashing him; there was a whole lane 2 empty if I had been that desperate to get home.
I shrugged and left him behind but to this day he probably thinks I was flashing him.
Paying attention to this when I re-joined the back of the queue my headlight most definitely seemed to be flickering imperceptibly, or jiggling over surface irregularities and being so much higher that most car headlights I figure it can seem like I am flashing folks; although he was the only one who took exception. When I got home I had to delve into my cowling to fit s a an HID kit I had been given and could find no physical reason, no loose bulbs, no loose adjusters, nothing.
Since then, I've paid a lot of attention to this when I am in the car and have noticed that most bike headlights do seem to flash, or flicker, when they come up behind me. Harsher suspension than cars? Higher lights? I have no idea but it has never bothered me, but I have noticed it is definitely a feature of most bikes.
