Front Side Marker

Years	Bulb Size

Description	Bulb Size
ANSI standard (US & Canada). Miniature wedge bulb (T10). 12V, 3.78W.	194

The Toyota 86 (2017-2020) uses the 194 bulb size for the front side marker position across all listed model years.
The 194 bulb is an ANSI-standardized type recognized in both the United States and Canada, which reflects a regulated specification rather than a manufacturer-specific one.
This bulb follows the T10 miniature wedge form factor, a base style that relies on two angled retention fins rather than a threaded or bayonet-style mount to hold the bulb in its socket.
The 194 operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs used in automotive exterior lighting, consistent with a marker rather than a primary illumination role.
Because the 194 is an ANSI-defined standard, aftermarket and OEM replacements carrying that designation are expected to share the same electrical and physical characteristics, supporting broad interchangeability within that specification.
