This invention is one kind may adjust the illumination light color the LED headlight, the department mainly becomes by the plural number point source combination, various point sources are contain have a reflection to cover, at least a illumination diode part and a control circuit; And this illumination diode part supposes firmly in the reflection coats, and has the high luminance and mixes the light characteristic, controls it by the control circuit to send out the different color light, when applies in head lamp's design, then (take white light as example) is had both the head lamp has the fog lamp (by Huang Guangwei example) function, but applies in the turn signal design, then can control this turn signal to assume Huang Guanghuo the thioindigo red the cut, may under the different driving environment, present the most remarkable caution light, ensures the traffic safety.
