Why the Bugatti Chiron Taillight Can Be A Single LED Strip Light

News Source: 

Luxury car brands often incorporate innovative car light designs, such as dynamic smart LED headlights or eye-catching tail light designs to give their cars a more distinctive look, but super race car Buggati Chiron’s single LED light strip taillight design had some in the industry scratching their heads.

Buggati was not the first car brand to come up with this taillight design, according to automotive media Jalopnik, four years ago the Volkswagen XL1 came up with a similar design concept for their taillight, but failed to pass the U.S. automotive lighting regulations.

The main difference between the two car brands design is the Volkswagen XL1 taillight was comprised of multiple lamps, and the area of each light covered less than 60% of the area circumscribing the projections of the emitting surfaces under ECE R 48 Abs.2.16.2 document of the United Nations Economic Commission for Europe.

In contrast, the Buggati Chiron complies with the 60% rule as specified in Abs.2.16.2:

"Two Lamps" or "an even number of lamps," means a single light-emitting surface in the shape of a band or strip if such band or strip is placed symmetrically in relation to the median longitudinal plane of the vehicle, extends on both sides to within at least 0.4 m of the extreme outer edge of the vehicle, and is not less than 0.8 m long; the illumination of such surface shall be provided by not less than two light sources placed as close as possible to its ends; the light-emitting surface may be constituted by a number of juxtaposed elements on condition that the projections of the several individual light-emitting surface on a transverse plane occupy not less than 60% of the area of the smallest rectangle circumscribing the projections of the said individual light-emitting surfaces.

Hence, the Bugatti Chiro’s taillight can pass U.S. automotive lighting regulations, while the Volkswagen XL1 cannot.

Aside from sporting a modern LED taillight style, the Bugatti Chiro which costs an astounding EUR 2.4 million (US $2.63 million)  added a complex LED lighting system, which can be programmed for special lighting scenarios, such as a welcome ceremony, the vehicle lighting system is designed for individual digital control, the car maker stated in a press release.
