The Acura ZDX uses 168 bulb size for both front and rear side marker applications. The replacement chart covers 2010 to 2013 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Acura ZDX uses the 168 bulb for both front and rear side markers across all listed model years, 2010-2013.
The 168 is classified as a miniature wedge bulb, designated T10 in the international bulb sizing system, where "T" refers to the tubular shape and "10" indicates the width in eighths of an inch.
The 168 bulb operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of side marker applications.
The 168 bulb conforms to ANSI standards, meaning it meets the standardized specifications recognized in both the United States and Canada.
The wedge base design of the T10 format means the bulb is held in its socket by the tension of the glass envelope itself rather than by a separate metal base, which is a common trait in small automotive lighting applications.
Because the Acura ZDX (2010-2013) uses the same bulb type in both the front and rear side marker positions, the 168 bulb is interchangeable between those two locations on the vehicle.
The T10 wedge format is shared by several bulb numbers beyond the 168, and not all T10-type bulbs carry identical wattage ratings, so wattage compatibility warrants attention when substituting alternatives.
