Additional Notes

The Triumph TR6 uses the 1895 bulb for the license plate position across all listed model years, spanning 1969-1976.
The 1895 is classified as a T5 miniature wedge bulb, meaning it has a wedge-shaped base that seats directly into a socket without a separate metal base or pins.
The 1895 operates at 12 volts and draws only 0.9 watts, placing it among the lowest-wattage bulbs in automotive lighting applications.
As an ANSI-standardized bulb, the 1895 designation is recognized across the United States and Canada, meaning the specification refers to a consistent, defined lamp regardless of manufacturer.
The T5 designation describes the bulb's tubular envelope width, where the number 5 represents five-eighths of an inch, making it a notably small form factor suited to compact license plate lamp housings.
Because the 1895 uses a wedge base rather than a bayonet or screw base, substituting a bulb with a different base type would require a socket adapter or replacement housing to achieve a proper fit in the Triumph TR6.
