This 2018 Buick Envision bulb size page is designed to help you verify the correct bulbs by lighting position before you buy replacements. Whether you are changing an exterior lamp or a cabin light, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.

For the 2018 Buick Envision, several lighting positions use LED assemblies, while others use replaceable bulbs such as 921, 194, 7441, 7444NA, 7440A, D3S, 2825, 98, 7065, H11 LED, H16 LED, and 9012 depending on the light and equipment. Because trim and lighting package can vary, always confirm the bulb type for your specific vehicle.

Fitment can differ by trim, market, and body style, so use the bulb chart as a guide and compare it with the bulb already installed in your Envision before ordering. This is especially important when choosing between halogen and HID headlight setups, or when replacing fog lights and other positions that may accept LED or halogen-style parts depending on the package. If you are planning an aftermarket LED conversion, make sure the bulb base, physical size, and beam pattern are compatible with the housing, and check for warning messages or flicker issues. When in doubt, remove the old bulb and verify the number printed on it before purchase.
