Volkswagen Squareback front and rear side marker bulbs utilize a 1895 bulb size specification. The replacement chart covers vehicle production spanning 1969 to 1973.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volkswagen Squareback uses the 1895 bulb for both front and rear side marker positions across the 1969-1973 model years.
The 1895 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a shared North American specification rather than a proprietary or regional standard.
The 1895 bulb belongs to the T5 form factor, which refers to a miniature wedge-base design. A wedge base holds the bulb in its socket through friction rather than a bayonet or screw mechanism.
The 1895 operates at 12 volts, which is consistent with the standard electrical system voltage found in most passenger vehicles of that era.
At 0.9 watts, the 1895 draws very low current, reflecting its role as a marker lamp rather than a primary illumination source.
Because the front and rear side marker positions on the Squareback share the same bulb type, a single 1895 bulb serves as a direct fitment for all four side marker sockets on the vehicle.
The T5 wedge designation indicates a bulb envelope width of approximately 5/8 of an inch, which is a compact profile suited to shallow or space-constrained housings typical of side marker assemblies.
The uniformity of the 1895 specification across all five model years covered suggests no mid-cycle changes were made to the side marker bulb fitment for the Squareback during this production period.
