Abstract: This disclosure relates to a light assembly for a motor vehicle. In some aspects, the techniques described herein relate to a motor vehicle, including: a light assembly including a first section, a second section, a third section, and a fourth section, wherein the first, second, third, and fourth sections are selectively illuminable independent of one another; a conspicuity lamp; and a controller configured to command the light assembly to illuminate at least one of the first, second, third, and fourth sections in phase with the conspicuity lamp.

Abstract: A rotary union (20) is disclosed for allowing fluid to flow between a first environment and a second environment where the first environment is rotating with respect to the second environment. The rotary union includes a pedestal (38) having a longitudinal pedestal bore (50) for transmitting fluid through pedestal (38); a housing (26) having a longitudinal housing bore (34) for transmitting fluid through housing (26). The diameter of longitudinal pedestal bore (50) of pedestal (38) is greater than the diameter of longitudinal housing bore (34) of housing (26). Housing (26) is coupled to the first environment and pedestal (38) coupled to the second environment; and rotating support structure (58, 60) is provided for coupling housing (26) and pedestal (38) with a gap (70) formed between a top portion of pedestal (38) and housing (26) with rotating support structure (58, 60) disposed below the gap with respect to the applicable gravity field.
