Spyder 13-16 Audi A4/S4 HID Model Only High-Power LED Headlights - Black PRO-YD-AA413HIDAP-BK

Spyder Auto is proud to present the Apex Series line. We have added integrated LED bulb technology directly into our housings. The light emitting diode is also called a luminescence diode or, in short, LED. LED stands for "light emitting diode", as it turns electrical energy into light. Physically, it is a cold-light source and an electronic semiconductor component part in optoelectronics. Its conductivity lies between that of conductors (e.g. metals, water, graphite) and non-conducting materials (e.g. non-metals, glass, wood). Spyder Auto has taken existing housing as well as new designs and added LED bulbs to the Low and High beams to maximize night time driving visibility. This is the highest quality and most technology equipped set of lights on the market.
