A device and method for alignment of an optical fiber with an output facet of a laser diode that are to be co-located on a mount, to obtain a substantially optimum coupling efficiency. More specifically, the oil has an oleic acid content of at least 55% by weight, a linoleic acid content of less than 25% by weight, a linolenic acid content of less than 14% by weight, a erucic acid content of less than 1% by weight, a palmitic acid content of less than 6% by weight, a stearic acid content of less than 2. A portion of the LEDs in the second section are illuminated to perform a running light function, and all of the LEDs in the second section are illuminated to perform a turn signal function. The nodes representing the processing units of the multiprocessor system may be interconnected to each other via a communication channel. These properties are of particularly advantageous since amplifiers in cell-phones are used in low power modes most of the time although they are designed to be most efficient at primarily the highest power levels.
