Buick Enclave 2019 Bulb Size
Bulb size chart
This 2019 Buick Enclave bulb size page is designed to help you verify the correct bulb type by lighting position, so you can replace the right lamp without guesswork. Whether you are changing a reverse light, license plate light, dome light, or a front turn signal, matching the bulb to the exact location is the safest way to shop.
The 2019 Buick Enclave uses LED lighting for many exterior and interior positions, while a few serviceable bulbs still use conventional part numbers. Because trim level, lighting package, market, and body style can affect fitment, it is always smart to confirm the bulb type before ordering. Use the chart on this page as a position-by-position reference for the most common bulb applications on this model.
For best results, compare the bulb listed here with the one already installed in your vehicle, especially if your Enclave has been modified or came with a different lighting package. Some positions may be LED from the factory, while others may use halogen-style replaceable bulbs, and aftermarket LED conversions can change the required fitment or create warning messages if the vehicle is sensitive to load. If you are unsure, remove the old bulb first and check the base, connector, and printed number before buying a replacement.
