Weak low beams & RH lamp won't come into alignment
 

1999 SLK 230 High beams are fine, low beams are very dull. Turned the adjustment screws to bring into better alignment but the right headlight is still in the trees. Is there an exploded view of the headlight assembly to see what adjustments need to occur to reel this light back into my world?? Are the headlights on these cars generally dim? Tks in advance
