The Isuzu VehiCROSS side marker requires a 194 bulb size for the lighting components located on the exterior of the vehicle. Data for the specified bulb covers the range from 1999 to 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 194 bulb is the sole bulb type across all side marker positions on the Isuzu VehiCROSS, covering both front and rear locations for the 1999-2001 model years.
The 194 bulb follows the ANSI standard recognized in the United States and Canada, classifying it as a regionally standardized automotive lamp.
It belongs to the T10 miniature wedge form factor, a designation that refers to the bulb's wedge-shaped base, which seats directly into a socket without a separate metal base or pins.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Its rated wattage of 3.78W places it in the low-power category, typical for side marker applications where illumination intensity requirements are modest.
Because the 194 bulb serves both the front and rear side marker positions across all three model years, a single bulb type covers all four side marker sockets on the vehicle.
The T10 wedge base is a widely used interface, meaning the 194 shares physical socket compatibility with several other bulb types that also use the T10 base, though wattage and light output may differ among them.
Substituting a T10-based bulb with a different wattage rating than 3.78W may affect compliance with side marker brightness regulations, as automotive lighting standards specify minimum and maximum intensity levels.
