This page helps you find the correct bulb sizes for the 2019 Buick Regal Sportback by lighting position, so you can match the right bulb before you buy. Whether you are replacing a headlight, fog light, brake light, reverse light, turn signal, or side marker, checking the bulb chart by location is the easiest way to avoid a mismatch.

The 2019 Buick Regal Sportback uses different bulb types depending on where the light is mounted, and some trims or lighting packages may vary by market and body style. Use the bulb list on this page as a fitment guide for the exact position you are servicing, especially if you are comparing front and rear exterior lights or replacing only one side.

Fitment can vary with trim level, factory lighting package, and whether the car has halogen or LED equipment in a given position, so it is smart to verify the bulb already installed before ordering. This is especially important if your Regal Sportback has been modified with aftermarket lighting, because conversion kits and retrofit housings may change the required bulb style or connector. For the best results, compare the old bulb, the socket, and the vehicle’s original setup before purchase, and make sure any replacement matches the intended use for halogen or LED applications.
