Vehicular headlamp having improved aiming mechanism

A vehicular headlamp comprising:

• a lamp body having a lamp chamber formed therein and a front opening;
• a lens covering said front opening;
• a main beam reflector and a sub beam reflector mounted in said lamp chamber;
• first and second aiming mechanisms for supporting and adjusting tilt angles of said main beam and sub beam reflectors, respectively, in a vertical direction, said first and second aiming mechanisms comprising first and second aiming screws, respectively, said first aiming screw having a portion extending outside said lamp body to allow external rotation of said first aiming screw;
• first and second counter pulleys fitted on each of said first and second aiming screws, respectively, so as to rotate with said first and second aiming screws;
• a belt entrained between said first and second counter pulleys, whereby effecting rotation of said first aiming screw from outside said lamp body causes corresponding rotation of said second aiming screw;
• third and fourth aiming mechanisms for supporting and adjusting tilt angles of said main beam and sub beam reflectors, respectively, in a horizontal direction, said third and fourth aiming mechanisms comprising third and fourth aiming screws, respectively, each of said third and fourth aiming screws having a portion extending outside said lamp body to allow external rotation of said third and fourth aiming screws;
• and first and second pivot fulcrums forming pivot points for said main beam reflector and said sub beam reflector, respectively.
