The Acura Integra front and rear side marker bulbs both utilize a 168 bulb size. The replacement chart covers vehicle production spanning 1986 to 1993.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Acura Integra uses the 168 bulb for both front and rear side marker positions across the 1986-1993 model years.
The 168 is classified as a miniature wedge bulb under the T10 form factor, which refers to its tubular wedge-base construction that allows direct insertion into a compatible socket without a separate metal base or pins.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of side marker and courtesy lighting applications.
The 168 carries ANSI standardization recognized in both the United States and Canada, meaning its electrical and physical characteristics conform to a defined industry specification rather than a proprietary standard.
Because the same bulb number applies to both the front and rear side marker positions on the Acura Integra, a single bulb type services all four side marker sockets on the vehicle.
The T10 wedge base format of the 168 is shared with several other bulb numbers in the miniature wedge family, such as the 194 and 147, though those alternatives carry different wattage ratings and are not interchangeable without verifying that the socket and circuit are rated for the differing load.
