Chevrolet Chevelle Glove Box Bulb Size

Additional Notes

• The 1895 bulb is an ANSI-standard miniature wedge type rated at 12V and 0.9W, while the 194 bulb shares the same wedge base family but operates at a higher wattage of 3.78W at 12V, making the two electrically distinct despite their similar form factor.
• The T5 envelope of the 1895 bulb is physically smaller than the T10 envelope of the 194 bulb, which affects socket fitment even though both use a wedge base design.
• The Chevrolet Chevelle used the 1895 bulb for the glove box across the 1964-1971 and 1973 model years, establishing it as the predominant bulb type in this application.
• The 1972 Chevelle glove box specifies the 194 bulb rather than the 1895, representing a departure from the fitment used in surrounding model years.
• Because the 1895 and 194 differ in both physical envelope size and wattage, they are not directly interchangeable without consideration of socket compatibility and circuit load.
• Both the 1895 and 194 bulbs conform to ANSI standards recognized in the United States and Canada, indicating standardized dimensional and electrical tolerances for each type.
• The 0.9W rating of the 1895 places it among the lower-output bulbs in the miniature wedge category, consistent with its use in a low-demand interior illumination application such as a glove box.
• The T5 designation of the 1895 refers to a tubular envelope with a nominal width of five-eighths of an inch, a sizing convention used across ANSI-classified miniature bulbs.
