Additional Notes

The 1895 bulb is the sole dome light bulb size listed for the Renault R12 across all model years covered by these specifications, spanning 1971-1977.
The 1895 is classified as a miniature wedge bulb under the T5 designation, meaning it uses a wedge-style base rather than a bayonet or screw fitting, and its tubular glass envelope measures 5/8 of an inch in width.
The 1895 operates at 12 volts and draws 0.9 watts, placing it among the lower-wattage miniature bulbs used in automotive interior applications.
The 1895 carries an ANSI standard designation applicable to the United States and Canada, indicating it conforms to a defined set of electrical and physical standards recognized in those markets.
The wedge base of the 1895 is retained in its socket by friction rather than by a locking mechanism, which is a characteristic of the T5 wedge form factor.
Because the 1895 is an ANSI-standardized part, it is generally interchangeable with any other bulb sharing the same 1895 designation, provided the replacement also meets the 12V and 0.9W ratings specified for the Renault R12 dome light application.
