The Citroen DS21 Pallas uses 1895 bulb size for both front and rear side marker positions. The replacement chart covers 1969 to 1972 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Citroen DS21 Pallas uses the 1895 bulb for both front and rear side marker positions across the 1969-1972 model years.
The 1895 is an ANSI-standardized bulb type, meaning its specifications conform to a defined North American standard used in the United States and Canada.
This bulb follows the T5 form factor, which refers to a miniature wedge-base construction. The wedge base is retained by friction rather than a bayonet or screw mechanism.
The 1895 operates at 12 volts, consistent with the standard electrical system voltage found in most passenger vehicles of this era.
At 0.9 watts, the 1895 draws very low current, which is typical of side marker applications where output requirements are minimal compared to headlamps or brake lights.
The identical bulb size across both front and rear side marker positions means a single bulb type serves all four side marker sockets on the DS21 Pallas.
The T5 wedge base format is not interchangeable with bayonet-style or screw-base miniature bulbs, even when voltage and wattage ratings are otherwise similar.
