The Mitsubishi Tredia front and rear side marker bulbs both utilize a 194 bulb size. The replacement chart covers vehicle production spanning 1983 to 1988.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Tredia uses the 194 bulb for both front and rear side markers across the 1983-1988 model years.
The 194 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized industry standard used across the United States and Canada.
It belongs to the T10 miniature wedge form factor, a compact bulb format that uses a wedge-shaped base rather than a pin or bayonet mount to make electrical contact within the socket.
The 194 bulb operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage is 3.78W, placing it in the low-power range typical of side marker applications, where continuous illumination is required without significant heat or current draw.
The identical bulb size across both front and rear positions means a single bulb type serves all four side marker sockets on the Tredia.
Because the 194 is an ANSI-standardized part, it is widely produced by multiple manufacturers and is not exclusive to any single supplier or vehicle brand.
The T10 wedge base format is shared by several bulb numbers beyond the 194, so fitment depends on matching the specific ANSI number rather than the base type alone, as wattage and filament ratings differ between T10 variants.
