A headlamp includes a base having a front face defining a first imaginary plane along the front face and a first imaginary line orthogonal to the first plane. A light assembly is rotatably secured about the front face to the base. The light assembly includes a bezel having a rear surface defining a second imaginary plane along the rear surface and a second imaginary line orthogonal to the second plane so that the intersection of the first line and the second line defines a rotation angle that varies with the rotation of the light assembly relative to the base, thereby changing the attitude of the headlamp light assembly.

1. A headlamp comprising:a base having a first surface adapted to bear against a user's forehead and defining a first plane and a first normal line to the first plane; a front face inclined downward relative to said first surface by a first angle; a light assembly including: a bezel having a rear surface rotatably supported relative to the front face of the base and a front surface inclined relative to said rear surface by a second angle; a battery case attached to said bezel and defining a closed volume between the battery case and the bezel; a battery located within said volume; a generally circular reflector disposed at least in part within said volume; a plurality of light emitters received in said reflector, said emitters adapted when energized to project a beam of light through the front surface of the bezel with the reflector internally reflecting light from the light sources to create a more uniform illumination field; and a switch connected between said battery and said light emitter; whereby rotation of the bezel relative to said base rotates the beam of light from a direction parallel to the normal line to a downward direction inclined relative to the normal line by the first angle plus the second angle. 2. The headlamp of claim 1 wherein said base is hollow and is adapted to receive a portion of said light assembly therein.3. The headlamp of claim 1 wherein said base further comprises a fastener for securing said headlamp to a headband or a helmet.4. The headlamp of claim 1 further comprising a crystal in contact with said bezel.5. The headlamp of claim 1 wherein said light emitters are light emitting diodes.6. The headlamp of claim 1 wherein said battery case has a removable cap affording access to the enclosed volume.7. The headlamp of claim 1 wherein said light assembly rotates about an axial pin interconnecting said base and said battery case.8. The headlamp of claim 1 wherein the rotation angle is between 130° and 230°.9. The headlamp of claim 1 in which the reflector includes a centrally located jewel.10. The headlamp of claim 1 wherein said light assembly rotates about a race incorporated into said base.11. The headlamp of claim 10 wherein a circumferential flange of said battery case engages said race.
