The ornamental design for a headlampreflector, as shown and described.
FIG. 1 is a perspective view of a headlamp reflector according to our new design;
FIG. 2 is a front elevational view of the headlamp reflector of FIG. 1; and,
FIG. 3 is a left side view of headlamp reflector of FIG. 1.
The rear of the headlamp reflector is unornamented.
FIGS. 1-3 illustrate a first embodiment of our novel design suitable for use on the left side of a vehicle. Our novel design also includes a second embodiment suitable for use on the right side of a vehicle, which is mirrored symmetrical to FIGS. 1-3 and therefore not separately illustrated.
The broken lines shown in the drawings illustrate portions of the headlamp reflector that form no part of the claimed design.
