These newly developed lighting units with a total length of 100mm and 3300mm are botht 10mm wide and equipped with warm-white LEDs on a white surface circuit board (picture shows preproduction prototype without white surface). Screwing holes with different distances allow the option for installation in various available passenger cars. If necessary the lighting units can be glued or taped or even shortened. All units already feature an integrated power buffer. If required a separate capacitor may be installed on the backside to increase the buffering time (for example when passing switches). The optimized technology allows to offer the LED lighting units in a double pack at a very reasonable price. The new improved LED lighting units replace the previous models 8124102, 8124502 and 8120001, 8121001, 8122001 and 8123001, which are no longer available or available only in low quantities.
