A vehicular exterior rearview mirror assembly includes a mirror casing, a mirror reflective element and a ground illumination module having a freeform optic, a ground illumination light source, and first, second and third icon light sources. With the vehicular exterior rearview mirror assembly mounted at the side of the vehicle and when the ground illumination light source is electrically powered to emit light, light emitted by the ground illumination light source that passes through the freeform optic illuminates the ground region adjacent to and along the side of the vehicle with a ground illumination intensity. When each individual icon light source is electrically powered to emit light, light emitted by the respective icon light source projects a respective projected image onto an icon region that is within the ground region. The respective projected images are individually projected to provide animated images projected onto the icon region.

A lamp for the rear of a vehicle is disclosed with a light transmissive cover having a red first illuminated surface area and a clear second illuminated surface area. It has a first LED light emitter located directly beneath the red first area, a second LED light emitter located directly beneath the clear second area, and a third LED light emitter, also located directly beneath said clear second area. The third red LED light emitter is for emitting red light through the clear second area simultaneously with light transmitted through the red first area, whereby the first and second areas are adapted to collectively form a contiguous red illuminated surface area.

Light-emitting diode (LED) packages, and more particularly broad electromagnetic spectrum LED packages are disclosed. Individual LED packages are disclosed that are capable of emitting various combinations of peak wavelengths across a broad electromagnetic spectrum, including one or more combinations of ultraviolet, visible, and infrared peak wavelengths. Such LED packages may also be broadly tunable across portions of the electromagnetic spectrum ranging from ultraviolet to infrared wavelengths. By providing such capabilities within a single light source provided by a single LED package, larger and more complex systems for broadband emissions that include multiple light sources, complex optical systems, mirrors, filters, and additional components may be avoided.
