Triumph GT6 Parking Light Bulb Size

Additional Notes

• The 1895 bulb is the specified parking light bulb for the Triumph GT6 across all listed model years, spanning 1967-1973.
• The 1895 is classified under the ANSI standard system, which is the bulb designation framework used in the United States and Canada.
• It belongs to the T5 form factor, a miniature wedge-base bulb type. The wedge base design means the glass envelope itself acts as the retention mechanism, with no separate metal base or pins required for socket fitment.
• The 1895 operates at 12 volts, consistent with the 12V electrical systems standard in automotive applications of that era.
• At 0.9 watts, the 1895 draws very low current, which is characteristic of parking and position light applications where continuous illumination without significant electrical load is the functional requirement.
• The T5 designation refers to the bulb envelope width expressed in eighths of an inch, placing the glass envelope at 5/8 of an inch wide. This compact size is typical of indicator and parking light housings with restricted interior space.
• Because the 1895 uses a wedge base, fitment depends on socket compatibility with that base type. Substituting a bulb with a different base style, such as a bayonet or screw base, would not be physically compatible with a wedge-type socket regardless of matching voltage or wattage.
