    The importance of complete supplemental lighting system was also more obvious with the continuous improvement of China′s "safe city" project. Firstly, the function and classification of the supplemental lighting system, the advantages and disadvantages of the present supplemental lighting system in the intelligent transportation system were expounded. To solve glare and overexposure these two problems in the supplemental lighting system, an anti-glare supplemental lighting system based on array light emitting diode mixed with infrared and white light was designed. Its hardware and software based on field programmable gate array (FPGA) adaptive algorithms were completed, and its effects were tested in the meantime. The test results show that its supplemental lighting effect is better than the white light, and the glare is significantly reduced. Besides, the binarization distribution of license plate images is even. And it is proved that the anti-glare supplemental lighting system could effectively solve the overexposure problem of the license plate.
