1. A rearview mirror assembly for a vehicle comprising:
- a mirror mounting structure for attaching to the vehicle;
a mirror supported by said mirror mounting structure; and
a lamp subassembly supported by said mirror mounting structure, said lamp subassembly comprising;
at least one LED device comprising at least one LED chip and a heat extraction element in thermal communication with said at least one LED chip; and
a thermally conductive reflector formed separate from said heat extraction element for reflecting light emitted by said at least one LED device, said thermally conductive reflector being disposed in thermal communication with said heat extraction element so as to function as a heat sink for said at least one LED chip.
