Volkswagen Fastback front and rear side marker bulbs utilize a 1895 bulb size across both positions. The replacement chart covers 1969 to 1973 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volkswagen Fastback 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, operating at 12 volts and 0.9 watts.
The T5 designation refers to the bulb's tubular glass envelope, with the numerical value indicating its width in eighths of an inch, making it one of the smaller bulb formats in automotive use.
The miniature wedge base of the 1895 bulb eliminates the need for a separate metal base or locking pins, as the glass envelope itself acts as the retention mechanism within the socket.
At 0.9 watts, the 1895 draws very low current, which is consistent with its role as a side marker rather than a primary lighting source.
The shared bulb specification across all five model years and both front and rear positions means a single bulb type services all four side marker sockets on any Fastback from this generation.
Because the front and rear side marker sockets on the Fastback both accept the same wedge base format, physical fitment alone does not confirm electrical compatibility when substituting alternative bulb types.
