Headlight dip setting
It is possible on S2 Elise to adjust the "Dip setting" on the Headlights, for right hand drive cars going to left hand drive countries.
In order to do this the headlight plastic cover needs to be removed. http://wiki.seloc.org/a/Remove_the_headlamp_cover
In photo four, you can see there are two small knurled bolts, there is another knurled bolt, this is under the wheel arch liner at the top, I took off the wheel arch liner, but it could be left on.
Adjusting the Dip setting
When you look directly at the Dip light fitting, you can see, a dirty bronze coloured piece of metal, that sits on the lower half of the lens, this is a small lever that has a small piece of black plastic on it, if this lever is gently pushed up, it moves a few mm, and this cuts off the extra bit of light that could shine in to other drivers eyes when you are driving on the left. It only produces a flat top beam, without the 'uplift' found on right hand drive dipped beam.
