Acura Legend front and rear side marker bulbs utilize a 168 bulb size across both positions. The replacement chart covers vehicle production spanning 1986 to 1988.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is the sole bulb type specified for the Acura Legend across all listed side marker positions and model years.
The 168 is an ANSI-standardized miniature wedge bulb, classified under the T10 form factor, and operates at 12 volts with a power draw of 4.9 watts.
The T10 wedge base design requires no locking tabs or bayonet pins for retention, as the bulb is held in place by friction within its socket.
The 168 designation follows ANSI standards recognized in both the United States and Canada, indicating a standardized specification for voltage, wattage, and base type.
The Acura Legend (1986-1988) uses the same 168 bulb size for both the front and rear side marker positions, meaning the same bulb type serves all four side marker sockets on the vehicle.
At 4.9 watts, the 168 falls within the low-wattage range typical of marker and clearance lighting applications, where high light output is not a primary requirement.
The T10 wedge base is a widely used form factor in automotive lighting, and the 168 shares this base with several other bulb numbers in the same family, though wattage and light output values differ between them.
Because multiple T10 wedge bulbs exist with varying wattages, substituting a bulb other than the 168 in these sockets may result in a mismatch with the original electrical load specification.
