The Buick Rendezvous front side marker bulb uses a 192 size, while the rear side marker bulb uses a 194 size. The replacement chart covers vehicle production years spanning 2002 to 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Buick Rendezvous uses the 192 bulb for the front side marker position across all model years from 2002-2007.
The rear side marker position on the Rendezvous requires the 194 bulb, also consistent across the full 2002-2007 model range.
Both the 192 and 194 are ANSI-standardized miniature wedge bulbs of the T10 type, recognized under both US and Canadian standards.
The T10 wedge base is a small, wedge-shaped base design that does not use a metal contact pin, relying instead on the wedge shape itself to make electrical contact within the socket.
Both bulbs operate on a 12-volt system, which is standard for automotive electrical systems in passenger vehicles of this era.
The 192 and 194 bulbs differ in wattage: the 192 is rated at 3W, while the 194 draws 3.78W, making them electrically distinct despite sharing the same T10 base type.
Because the 192 and 194 share the T10 wedge base, they are physically interchangeable in terms of fitment, but the wattage difference means they are not identical replacements for one another.
The front and rear side marker positions on the Rendezvous are specified for different bulb numbers, so substituting a 194 in a front socket or a 192 in a rear socket would result in an off-specification installation.
