Headlight adjustment needed

[Pointshape]

Hi all
My front lights in my plus 2 have a mind of their own…
As I drive along they go up and then will come down again. When Inpark, they raise up after a short time. They stay on and up in the dark when they are turned on luckily!!
I am based in Norfolk/Cambs.
Can anyone suggest anyone who Incan take it to who can make the correct adjustments to stop this from happening please?

I'm in Thetford and I have a good friend locally who looks after my Caterham and Elan who I'm sure would look at it for you. Noticed you're in Cambs/Norfolk, where exactly?

If the headlights go down when you rev, and go up when you idle, likely the anti return valve in the hose just downstream of the cylinder head is faulty ( missing ?) .
