Additional Notes

The Renault R18i uses the 211-2 bulb for its license plate light across all listed model years, spanning 1981-1986.
The 211-2 is an ANSI-standardized bulb type, meaning its physical and electrical specifications conform to a defined North American standard used in the United States and Canada.
This bulb is a festoon type, which refers to a cylindrical lamp that mounts by pressing its end caps into spring clips rather than inserting into a socket.
The 211-2 measures 41mm in length, which is a critical fitment factor, as festoon bulbs must match the spacing of the spring clips in the housing.
It uses an SV8.5 base, a designation that describes the end cap style and the 8.5mm width of the metal contacts at each end of the bulb.
The 211-2 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage is 12W, which places it at the higher end of typical license plate bulb outputs for incandescent festoon lamps.
Because the 211-2 is an ANSI-designated part, substitutions should match the 41mm length and SV8.5 base to ensure proper fitment within the R18i license plate housing.
