Abstract
A headlamp includes heat sink structure for positioning a light emitting diode at an angle offset from the longitudinal axis of the headlamp and a reflector lens subassembly including a reflector portion and a light transmissive portion. The reflector portion includes a reflective surface for directing light from the light emitting diode towards the light transmissive portion. The reflector lens subassembly includes an upper rim with alignment features for engaging the perimeter of the heat sink structure to define a sealed three-dimensional space within the headlamp and to facilitate positioning of the light emitting diode with respect to the reflector lens subassembly.
