Abstract: The evolutionary vehicle LED lighting apparatus is essentially formed of a power supply circuit for supplying the power to the apparatus, a microcomputer detecting and control unit, and a LED driving circuit installed at the output side of the power source. Upon detecting the power is on, the hardware built in the microcomputer detecting and control unit works to actuate the LED driving circuit so as to evolutionarily turn on the LEDS outwardly until, I all the LEDS are lit. Upon detecting the power is shut out, the microcomputer detecting and control unit actuates the LED driving circuit to turn off the LEDS in the reverse manner as they have been turned on thereby achieving the legibility and alarming effect of the vehicle lights rhythmically including both the brake light and the directional lights, also the operation method of this apparatus is disclosed.
