The LEDs for this high-performance light system came from Osram. Each of the main headlights uses six “Oslon Black Flat S” LEDs (3-chip version), which are very compact and particularly bright. For the auxiliary headlights on the BMW M8 GTE, the “Olstar Headlamp” was selected and specifically developed for applications requiring bright light and provides a seamless, white light. In order to keep the weight as low as possible, the housings for the main and auxiliary headlights are made of carbon fibre, as are the reflectors, which are then coated with chrome. The iconic double circular lights, with two LED rings, serve as daytime running lights and indicators. While the heat sink element in the main headlights is relatively unspectacular, the cooling element in the auxiliary headlights is far more sophisticated. It not only holds the LEDs, but also leads hot air away from the LEDs via channels and cooling fins. This hot air could otherwise affect the performance of the LEDs, or even result in them failing completely. When designing the cooling elements and headlight housing, the very latest Additive Manufacturing 3D printing techniques were used. That way, it was possible to produce a set of four headlights in just 72 hours. The rear lights are identical to those used in the production counterpart. “We did not make any changes to the rear lights, as they are already nice and effective, so we were able to transfer them 1:1 to the racing car,” says Bichler.
