The present disclosure relates to a novel motor vehicle illuminating headlight. The motor vehicle illuminating headlight includes a power supply driver electrically connected with structure modules. The surfaces of the structure modules are in contact with an aluminum pressing strip, the aluminum pressing strip being connected with a radiator fixedly connected with the power supply driver, the outer side of the radiator being connected with a PC lens, and the other side of the radiator connected with a support. Advantageously, the illuminating use efficiency is improved, the application range is wide, automatic switching between a main illuminating light and atmosphere lights is achieved, and therefore better illumination is provided, energy conservation and environmental protection are facilitated, and the motor vehicle illuminating headlight has good ornamental and economic value.
