Additional Notes

The 1816 bulb is the specified license plate bulb size for the Merkur Scorpio across its 1988-1989 model years.
The 1816 is classified as a miniature wedge bulb, using a T3.25 designation, which refers to the tubular glass envelope measured in eighths of an inch.
The wedge base design means the bulb is held in place by the socket gripping the base of the glass envelope directly, with no separate metal base or pins.
The 1816 operates at 12 volts and draws 4 watts, placing it among the lower-wattage bulbs used in automotive exterior lighting applications.
The 1816 carries ANSI standardization, meaning its physical and electrical specifications are defined by a recognized North American standards body and apply uniformly across manufacturers in the US and Canada.
Because the 1816 follows an ANSI standard, bulbs carrying that designation from different manufacturers are expected to share the same voltage, wattage, and physical form factor.
