Buick Lucerne 2008 Bulb Size
Bulb size chart
This 2008 Buick Lucerne bulb size guide helps you verify the correct bulb by lighting position, so you can replace a failed lamp without guessing. Whether you are changing an exterior signal bulb or a small interior light, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
Because trim and lighting equipment can vary, the same Lucerne year may use different bulbs depending on body style, market, or package. Use this page to compare the bulb chart by position before you buy, especially if you are replacing headlights, fog lights, brake lights, or interior courtesy bulbs.
For best results, confirm the installed bulb before ordering, especially on vehicles with optional lighting packages or previous aftermarket repairs. Some positions on the 2008 Buick Lucerne may be halogen from the factory, while others may have been converted to LED by a previous owner. That matters because an LED replacement may fit the socket but still need the correct polarity, load resistor, or CAN-bus compatible design to work properly. If you are upgrading from halogen to LED, check beam pattern, brightness, and legal use for your state or province. When in doubt, remove the old bulb and compare the base style and markings before purchase.
