Here are a couple of pictures of the quality installation on the 07 Contessa. Bulb removal and replacement is a simple twist and pull. I find no adjustment screws on mine, same as Robert says.

My experience with the "all in one" plastic headligh units is that they can't be adjusted, so will retain their aim for as long as you haven't crunched that corner.  That's what I have on both of my cars.  If you have a misalignment of the light, you also have misalignment of everything else on that corner, so really should go to a body shop.

On my Contessa, it is older, so can be adjusted.  The "driving lights", however, are a different story. I have a switch on the dash labelled "driving lights".  I noted the pool of light from these driving lights illuminates the road from 4 ft in front to 8 ft in front.  OK, they should be easy to adjust, right?  Ha!  The style of light used, is designed to be mounted from above or below, so the mount can pivot horizontally, and twist for vertical adjustment.  You would assume the assembly persons at Beaver would be able to do that right.  But no, they were mounted to the vertical surface at the back of the mount recess, so there was no sideways adjustment whatsoever, and the vertical adjustment was limited by the body of the light hitting the back of the recess when elevated to the position I found them in.  The only adjustment left was to drop them, to shine on the pavement right under their mount!  Off they came, new holes in the correct surface, and I now have driving lights... except now I see the lights are not really driving lights, but just cheapo floodlights, so another trip to the store will be required before they are right.  

Surprised no previous owner, in 13 yrs, has dealt with this.
