UD 2300 front and rear side marker bulbs utilize 67 and 168 bulb sizes respectively. The replacement chart covers vehicle production spanning 1995 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The UD 2300 uses bulb size 67 for the front side marker across the 1995-1998 model years.
The 67 bulb is an ANSI-standard single-filament type rated at 12V and 8W, fitted with a BA15s bayonet base.
The BA15s base is a single-contact bayonet fitting, which is not interchangeable with dual-contact bayonet bases such as those found on the 1157 or 2057 bulb families.
The 67 bulb is a lower-wattage variant of the 1156, sharing the same BA15s base but drawing less power, which means the two are not direct drop-in replacements for one another despite their physical similarity.
The rear side marker on the UD 2300 uses bulb size 168 across the same 1995-1998 model years.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W, held in place by the tension of the socket rather than a bayonet or screw mechanism.
The front and rear side marker positions on the UD 2300 use different bulb types, with the front requiring a BA15s bayonet base and the rear requiring a T10 wedge base, making the two non-interchangeable.
Both the 67 and 168 bulbs conform to ANSI standards recognized in the United States and Canada.
