The Oldsmobile LSS side marker utilizes a 194 bulb size for the lighting component located on the exterior of the vehicle. Data for the specific bulb requirements covers the period from 1996 through 1999.
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 size specified for the Oldsmobile LSS across all side marker positions for the 1996-1999 model years.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, placing it within a regulated specification framework for miniature automotive lighting.
It is classified as a T10 miniature wedge bulb, a form factor defined by a wedge-shaped base that seats directly into a socket without a separate metal cap or bayonet pins.
The T10 designation refers to the bulb's tubular envelope width, expressed in eighths of an inch, making it a relatively compact light source suited to side marker applications.
Operating voltage is rated at 12V, consistent with the standard electrical system voltage found in conventional passenger vehicles of this era.
Power consumption is 3.78W, placing the 194 in the low-wattage category typical of position and marker lamps rather than high-intensity illumination sources.
The front and rear side marker positions on the LSS share an identical bulb size for all four model years covered, meaning a single bulb type services both locations on the vehicle.
The wedge base of the T10 format is not interchangeable with bayonet-base or festoon-style sockets, and substitution with physically different base types would require socket modification.
