Just incase anyone is having a similar problem, as once again it happened and i had again one dipped headlight signalling ufos the other pointing at the first foot of tarmac in front of the car lighting the way for weary hedgehogs and the like.

this is a bit of a bodge (temporary fix) but the headlight pointing upwards responded to the adjuster switch on the dash luckily so i put it too setting No 3 and there was just enough in the hex adjuster on the rear of the both headlights to focus the dipped beams! i then pulled the two fuses from the interior dash fuse box. they haven't budged since! so basically now its set and forget for me. im somewhat annoyed as they were perfectly set full and high beam as per my previous post before the gremlins came out to play again!

P.S looking at the rear of my headlights where the the bulbs go in on the near side headlight it is badly melted so the solution in my case would be new headlight units. the previous owner had some cheap aftermarket L.E.D bulbs fitted which i have a suspicion along with a wire shoved into the fuse no 8 on the fuse board which may have caused this problem to begin with.
