An automotive combined turn signal and tail/stop lamp () having co-axial transparent collimating inner and outer light guides (). Inner collimating light guide () receives light from a yellow LED (), outer collimating light guide () receives light from red LEDs (), the yellow and red LEDs located in thermal communication with a common heat sink (). Mirror optics () reflect light from respective light output prisms () of the inner and outer light guides outward to nested reflectors on the automobile. Electrical conductors () between the light guides () can feed power from a PC board () to supply additional light sources within an RCL housing, such as white back-up light.

Combination turn and tail multi-color LED lamp

An LED lamp () has a housing () with an interior wall () defining a cavity (). An LED light source () is positioned in the cavity () and project light in a forward direction. A reflector () having a reflective surface (), a forward opening () and a rear opening () surrounds the light source () and a complex lens () closes the forward opening. The lens () comprises a first optical refractive element () arranged around a peripheral edge () and a second optical refractive element () centrally located on the lens (); the first optical refractive element () including a plurality of flute lenses () and the second optical refractive element () comprising a concavo-convex lens ().
