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.
