Buick Riviera 1999 Bulb Size
Bulb size chart
This page for the 1999 Buick Riviera helps you verify the correct bulb size by lighting position, so you can match the right replacement before you buy. Whether you are changing a headlight, interior lamp, or rear signal bulb, checking the exact location is the easiest way to avoid ordering the wrong part.
The 1999 Riviera uses a mix of common wedge bulbs and specific fitments across the exterior and interior lighting system. Because trim level, lighting package, market, and body style can affect what is installed, use the bulb chart below as a guide and compare it with the bulb already in your vehicle when possible.
For best fitment, confirm whether your Riviera is using a standard halogen bulb or an LED upgrade, since aftermarket conversions can change beam pattern, brightness, and connector style. Some positions may also vary with trim or package differences, so it is smart to inspect the installed bulb before ordering, especially for courtesy, interior, and rear lamp locations. If you are switching to LED, make sure the replacement is compatible with the socket and any vehicle electronics, and remember that a bulb listed for this year may still need a different style or resistor setup in an aftermarket conversion.
