Whether you are replacing a headlight, brake light, reverse light, or a small interior bulb, checking by location is the easiest way to avoid ordering the wrong part.
The 2009 Buick Lucerne uses a mix of standard halogen bulbs and smaller interior and exterior bulbs, and some fitments can change with trim, body style, or lighting package. Use the bulb chart on this page as a quick reference for the most common bulb locations on the vehicle, then compare it with your existing bulb before buying.
For the best fitment results, always confirm the trim and package details for your specific Lucerne, since some lighting setups can vary by market and body style. If you are considering LED replacements, remember that a direct LED swap may change brightness, beam pattern, or warning behavior compared with the original halogen bulb. Aftermarket conversions can also require additional parts or compatibility checks, especially for fog lights and exterior signal lamps. Before placing an order, remove the installed bulb and compare the base, connector, and markings so you know the replacement matches the actual part in the vehicle.
