Is the headlight adjuster motor working on both sides ??

The adjusters plastic arm tends to fail, or the entire unit or bulb might be loose if both clips are not in place.

By flickering do you mean the beam pattern's moving about (so they sound loose), or is it they appear to be switching on & off (so it sounds electrical)?

If electrical it could be one of the relays in the lighting control unit (under the dash to the RHS) needs replacing.

Not dear, reasonably easy to get to and do (lots of posts on here, I put one up a couple of months ago - check my username for it)

If it's the beam's wabbling then as was posted, it could be the adjusters that are loose.

Post some further info and I'm sure someone on here can help you.
