Ford Festiva front and rear side marker bulbs utilize 168 and 194 bulb sizes across different positions. The replacement chart covers 1988 to 1993 model 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 Ford Festiva side marker system uses two bulb types across its production run: the 168 and the 194. Both are ANSI-standard miniature wedge bulbs sharing the T10 form factor and a 12-volt operating voltage.
Although the 168 and 194 share the same T10 wedge base and voltage rating, they are not identical. The 168 operates at 4.9 watts, while the 194 operates at 3.78 watts, making them distinct specifications despite their physical similarity.
The front side marker on the Ford Festiva uses the 168 bulb for 1988-1989 and 1991-1993. The 1990 model year is the sole exception, requiring the 194 instead.
The rear side marker on the 1988-1989 Festiva takes the 168 bulb. From 1990-1993, the rear position transitions to the 194.
On the 1990 Festiva, both the front and rear side marker positions share the 194 bulb, making it the only model year where a single bulb type covers both side marker locations.
On 1988-1989 models, both front and rear side marker positions use the 168 bulb, again representing a year range where a single type serves both locations.
The T10 wedge base is a tool-free, push-in fitting. Its use across both the 168 and 194 types means the sockets themselves are physically compatible with either bulb, though wattage differences remain a relevant factor for correct replacement.
