A vehicle light device includes a primary light source configured to emit first light having wavelengths in a first wavelength range, and a conversion element including an input end and an output end, the input end being optically coupled to the primary light source. The conversion element includes a nonlinear optical medium configured to convert at least a portion of the first light to second light having wavelengths shifted from the first light such that the output end outputs collimated light having a broad wavelength range including wavelengths of the first light and wavelengths of the second light. An outer lens is optically coupled to the output end of the wavelength conversion element and configured to transmit the output light as white light for illuminating a path of a vehicle.
