Headlight Adjustment???????????
Discussion
Hi folks,
The Elise failed it's MOT on Friday, and after a weekend spent changing brake pads and bulbs, the only thing it failed on was the headlights being too high.
I searched seloc techwiki, and i have a copy of the workshop manual. I have found references to removal and refitting, easy enough, accessed from the front arch. Also found details on adjustment for driving abroad, by covering the top of the beam with a neat inbuilt adapter.
However i couldn't find anything specific on height adjustment.
Any ideas? Anyone failed an MOT before for headlights too high? are they adjustable?
Many thanks for any help.

Yep, mine failed on headlights a couple of weeks ago.
It is no problem to adjust.
Remove the headlight cover. To do this you have to remove the inside front wheel arch cover, you will then find the allen bolts to remove the light unit cover. Remove the allen bolts and the cover will lift out. To adjust the lights, I park in the garage with the door closed and shine the lights on the door so you can set height. I also draw a line on the light pattern so you can see the change. There are some 8mm nuts around the corners of the light you are going to adjust. Turn these to adjust.

My rear end is fine thank you very much 
I called into the (friendly) test station that did it and asked them how far out it was (they also failed it on pads (less then 1.5mm) but after removing them i found they had 2.5mm+ )
I suggested i put lead in the footwells - he said his fail on the headlight height was so marginal that would probably work.
Alternatively let some air pressure out the fronts and that's a pass too.
I guess that over time, vibration will make anything that is designed to move, move a little. Short of loctiting the adjusting mechanism in place i guess they won't need doing again for 5 years/50k miles.

Steve,
you shouldn't need to remove the liner to access the bolts. My headlights were miles out when I bought my car back in May (early S2 - dips too low and mains way too high!) and I've had the covers off many times to try and perfect the aim. What I did notice is that when the covers are off, the lamps sit slightly higher so when you check the beam it looks OK... until you refit the covers and they're still wrong. I assume that all cars are like that, not just mine!

.... or ... you could adjust them ... ?

Thanks Graeme, but too late. I measured them fitted (marked on garage door), then removed them, and held in position. Then adjusted whilst being held. Refitted and they're where they should be relative to the marks.you shouldn't need to remove the liner to access the bolts.
