Automotive illumination fibers serve interior and exterior lighting, improving appearance and night-driving safety. They transmit between distant points or through difficult curves and corners. Materials: plastic optical fiber (POF), 1. relatively inexpensive; 2. flexible; 3. easy to install and form; 4. generally decorative or ambient lighting. Glass fiber, 1. better transmission and temperature tolerance; 2. higher cost and less flexibility; 3. high optical quality or long-distance delivery; 4. for most automotive uses, plastic remains more common because of cost effectiveness and flexibility. Automotive fibers are specialized, efficient, reliable, energy-saving sources with an increasing role. The source anticipates broad prospects and gradual replacement of incandescent lamps as a preferred automotive light source.

Headlights: an important automotive lighting device. LEDs or xenon lamps generally supply light, which automotive illumination fibers transmit to the headlight lens for projection onto the road ahead. Tail lights: another important device, generally using LEDs or incandescent lamps with fibers transmitting light to the tail-light lens for projection onto the road behind. Turn indicators: important signal lights, generally using LEDs or incandescent lamps with fibers transmitting light to the indicator lens for projection onto the road to the side. Brake lights: important signal lights, generally using LEDs or incandescent lamps with fibers transmitting light to the brake-light lens for projection onto the road behind.
Heat resistance: automotive illumination fibers must withstand engine-compartment temperatures. Vibration resistance: they must tolerate vibration during driving. Flexibility: they must bend and wind to accommodate complex vehicle structures. High brightness: sufficient output is required for automotive lighting. High brightness is reiterated: efficient transmission to vehicle lamps provides the required illumination. Energy saving: substantially lower energy consumption than conventional incandescent lighting. Long life: tens of thousands of hours, far exceeding incandescent lamps. Heat resistance is reiterated: engine-compartment temperatures do not damage the fiber. Vibration resistance is reiterated: driving vibration does not damage it. Flexibility is reiterated: good bending and winding accommodate complex vehicle structures.
