Sterling 825 front and rear side marker bulbs use 194 and 1895 bulb sizes respectively. The replacement chart covers 1987 to 1988 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 Sterling 825 uses two distinct bulb types across its side marker positions: the 194 at the front and the 1895 at the rear, covering model years 1987-1988 for both positions.
Both the 194 and 1895 are ANSI-standardized bulbs recognized in the United States and Canada, meaning they conform to a defined set of electrical and physical parameters shared across many vehicle applications.
The 194 bulb follows the T10 wedge form factor, which refers to a miniature wedge-base construction roughly 10mm in width, and operates at 12V with a power draw of 3.78W.
The 1895 bulb follows the T5 wedge form factor, a narrower miniature wedge base approximately 5mm in width, and operates at 12V with a significantly lower power draw of 0.9W.
Although both bulbs share a wedge-base design and a 12V operating voltage, the T10 and T5 form factors are physically incompatible with each other, meaning the front and rear marker sockets on the Sterling 825 are not interchangeable.
The power difference between the 194 (3.78W) and the 1895 (0.9W) reflects their respective roles, with the front marker drawing notably more power than the rear.
