The Buick Skyhawk front and rear side marker bulbs both utilize a 194 bulb size across all model generations. The replacement chart covers vehicle production spanning 1975 to 1989 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 Buick Skyhawk uses the 194 bulb for both front and rear side marker positions across all specified model years from 1975-1989.
The 194 is an ANSI-standardized bulb type recognized across the United States and Canada, meaning it conforms to a defined set of electrical and physical characteristics shared by all compliant manufacturers.
The 194 bulb follows the T10 miniature wedge form factor, which uses a tapering plastic base that wedges directly into a socket rather than relying on a bayonet or screw-type connection.
The 194 operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs used in automotive applications, consistent with its role as a marker rather than a primary lighting source.
Because the front and rear side marker positions on the Skyhawk share the same 194 bulb specification, a single bulb type serves both locations on the vehicle.
The T10 wedge base of the 194 is a widely used standard in automotive marker and courtesy lighting, and aftermarket equivalents from various manufacturers are generally produced to the same ANSI ratings.
The 194 bulb specification remains unchanged across the entire 1975-1989 model year range covered in these specifications, indicating no variation in socket type or electrical requirement between earlier and later Skyhawk production.
