The multi-color light lamp has a base divided into a plurality of segments. The three segments are spaced at 120 degrees. More or less segments can be used. An LE D is positioned in each segment, the LED in each segment emits a color distinct from the light emitted by the LEDs in the other segments. If the lamp is to be used for automotive purposes, the LED in a first segment emits red light as a taillight and a st op light, the LED in a second segment emits yellow light a turn signal lamp, and the LED i n the third segment emits white light as a backup light. A light pipe is operatively associated with the LEDs in each segment for directing emitted light away from the base. The LEDs (preferably two per segment) are mounted upon a thermally efficient printed circuit board such as a flex-on aluminum board. |
