1. A vehicle lamp assembly comprising:
- a solid state first light source emitting light having a dominant wavelength less than about 530 nm when a DC potential is applied thereto; and
a second light source, wherein said second light source projects light having a dominant wavelength less than about 635 nm, and wherein the vehicle lamp subassembly emits two different and complementary spectral bands that together form white light.

Abstract
A light emitting assembly having a first light source and a second light source. The first and second light sources are oriented such that when the first and second light sources emit light, light emitted from the first and second light sources overlaps and is capable of forming white light. The light emitted from the first light source exhibits color coordinates different from the light emitted from the second light source. Also disclosed is a license plate illuminator having an LED device capable of emitting white light.
