Additional Notes

The 168 bulb is the sole license plate bulb size listed for the Acura SLX across the 1996-1999 model years.
The 168 bulb follows the ANSI standard, which is the American National Standards Institute classification system used to define bulb specifications in the United States and Canada.
It is a T10 miniature wedge bulb, a form factor defined by a wedge-shaped base that connects directly into a socket without a separate metal base or pins.
The T10 designation refers to the bulb body width expressed in eighths of an inch, placing it in the smaller range of miniature automotive bulbs.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Its rated wattage of 4.9W places it among the lower-draw bulbs in automotive applications, typical for non-illumination roles such as license plate lighting.
The consistent fitment of the 168 across all four listed model years indicates no mid-cycle change to the license plate lamp socket or housing during that production span.
The wedge base of the T10 form factor is not mechanically interchangeable with bayonet or festoon base bulbs, even when voltage and wattage ratings are similar.
