Should my xenon headlights be adjusting continuously?

[GlenH]

When I switch the ignition on (engine off) on my 172 I can hear what sounds like the drivers side xenon headlight constantly adjusting (the passenger side one seems quiet though).

Is this normal, or is it a problem with the sensor (which I believe is on the rear axle)? But if that's the case, why is only one of the lights making the noise?

Yes they auto adjust

Mine have both popped out of the casings when I changed bulbs Gotta take them apart I think.

Should they be doing it continuously though (it doesn't seem to stop no matter how long I leave it)?

They will always be adjusting if the suspension is moving around, if the car is standing still the should eventually stop

instead of taking them apart , adjust the manual adjustor all the way and it should pop itself back in mate , assuming it isnt broke

Or he could take them out, cut them up and fix them like a smart guy did with the ones you had/i have :rasp:

I think they're beyond that tbh, thanks though. They currently flail about and are very loose. kind of jammed them in place but im lighting up the night sky usually...
