The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1895 bulb is the sole bulb type specified across all side marker positions on the Austin Marina for the 1973-1975 model years.
The 1895 is classified as a T5 miniature wedge bulb, meaning it uses a wedge-style base rather than a bayonet or screw fitting, and its envelope follows the T5 tubular form factor.
The 1895 operates at 12 volts with a power draw of 0.9 watts, placing it among the lower-wattage miniature bulbs used in automotive marker lighting.
The 1895 conforms to ANSI standards applicable in both the United States and Canada, indicating it was specified to meet North American regulatory requirements for side marker visibility.
The Austin Marina (1973-1975) uses the same 1895 bulb for both the front and rear side marker positions, meaning the two locations share a common fitment rather than requiring different bulb types.
The wedge base of the 1895 is retained by friction within its socket rather than by a locking twist, which is a characteristic of the T5 wedge form factor and affects how the bulb is seated and removed.
