For the 2009 Buick Enclave, both the low-beam and high-beam headlights use D1S bulbs. The supplied fitment data does not list a separate bulb by headlight style, so confirm the existing headlamp assembly before ordering.
Fog-light fitment is listed as either H11 LED or H16 LED. Check the connector and the bulb currently installed, since these are separate options rather than a single combined fitment.
