The Cadillac Escalade side marker utilizes a 194 bulb size for the lighting components located on the exterior of the vehicle. Data for the specified bulb covers the range from 2002 to 2006.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Cadillac Escalade uses the 194 bulb for its front side marker across all listed model years from 1999-2014, with the sole exception of 2001, which is not present in the front side marker data.
The 194 bulb is an ANSI-standardized type recognized in both the United States and Canada, meaning it conforms to a defined electrical and physical specification rather than being a proprietary or manufacturer-specific part.
The 194 is classified as a T10 miniature wedge bulb. The T10 designation refers to a tubular glass envelope roughly 10/8 of an inch wide, and the wedge base type means the bulb is held in its socket by the glass base itself rather than by metal pins or a bayonet fitting.
The 194 bulb operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of marker and courtesy lighting rather than primary illumination functions.
The rear side marker positions on the Cadillac Escalade also use the 194 bulb, covering model years 1999-2006. This means the front and rear side marker positions share the same bulb type across all years where both are listed.
Because the front and rear side marker positions use the same 194 bulb, a single bulb type serves both locations on the Escalade models covered by these specifications.
The T10 wedge format is a widely used base type across many vehicle makes and models, which means 194 bulbs are broadly available as direct-fit replacements without socket modification.
At 3.78 watts and 12 volts, the 194 draws approximately 0.315 amperes. This low current draw is consistent with its role as a side marker, a lighting function governed by federal standards requiring visibility rather than high output.
