LED lamp assembly particularly adapted for automotive applications that utilizes one or more standard replaceable LED bulbs with changeable optics to make multiple beam patterns. The reduced-image data is subjected to a fluency transform to generate expanded-image data partitioned into second blocks corresponding to the first blocks. The first electrodes are parallel to the second electrodes in each domain. The first and second control gates extend in the column direction. In this way, it is possible to suppress entering of water into the first waterproofing walls. A transmission and the fan shaft are installed to a front frame assembly.
