Alfa Romeo Milano front and rear side marker bulbs require a 168 bulb size for proper illumination. The replacement chart covers 1987 to 1989 model 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 Alfa Romeo Milano uses the 168 bulb for both front and rear side markers across its 1987-1989 model years.
The 168 is a miniature wedge-type bulb, classified under the T10 form factor, which refers to a tubular bulb roughly 10mm in width with a wedge-style base that requires no separate socket retainer.
The 168 operates at 12 volts with a power draw of 4.9 watts, placing it in the low-wattage range typical of side marker applications where continuous illumination is required without significant heat output.
The 168 bulb conforms to ANSI standards recognized in both the United States and Canada, meaning it meets a defined set of electrical and physical tolerances established for the North American market.
Because the front and rear side marker positions on the Milano share the same bulb specification, a single bulb type serves all four side marker sockets on the vehicle.
The T10 wedge base is a widely used form factor, and bulbs carrying that designation from different manufacturers may vary in wattage or voltage rating, so the 168-specific rating of 12V and 4.9W represents the correct specification for this application rather than the T10 designation alone.
