Plymouth Volare front and rear side marker bulbs both utilize a 168 bulb size. The replacement chart covers 1976 through 1980 vehicle 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 Plymouth Volare uses the 168 bulb for both front and rear side marker positions across the 1976-1980 model years.
The 168 is an ANSI-standardized bulb recognized in both the United States and Canada, conforming to a shared North American specification.
It belongs to the T10 form factor, a miniature wedge-base design that does not use a separate metal base or locking pins, relying instead on the wedge shape of its glass envelope to seat within the socket.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
Its rated power draw is 4.9 watts, placing it in the low-wattage range typical of side marker applications, which are indicator lamps rather than primary illumination sources.
Because the front and rear side marker positions share the same bulb size on the Plymouth Volare, a single bulb type services all four side marker sockets on the vehicle.
The T10 wedge base is a widely produced form factor, and the 168 designation is interchangeable with other bulbs sharing the same ANSI rating, voltage, wattage, and base type, provided those values match exactly.
Wedge-base bulbs such as the 168 are removed and installed by pulling straight out of and pushing straight into the socket, without any rotation required.
