Questions
What is the Buick Regal Sportback low-beam bulb?
2019 Buick Regal Sportback stores H7 for the halogen low beam. Choose the LED headlight configuration separately when the chart lists one. These are not installed together.

2019 stores H7 for the halogen high beam.
What fog light bulb does the Buick Regal Sportback use?

What turn-signal bulb does the Buick Regal Sportback use?

What brake-light bulb does the Buick Regal Sportback use?
Halogen-configuration brake lights in 2019 store 64136.
What does an LED record mean?
A stored part of LED means that configuration is recorded as an LED assembly. It is not a replaceable halogen bulb, and this page does not sell an LED conversion as the OEM bulb for that assembly.
Can I substitute a nearby bulb number?
No. H11 and H11B stay different. 9005 and 9006 stay different. This page matches the stored designation and does not swap in another bulb to fill the product list.
Does a catalog match guarantee the bulb fits?
A designation match means the product is filed under that bulb number and technology. It does not prove the lamp, socket, or vehicle configuration. Check the bulb in the housing before ordering.
How do I verify the replacement?
Read the number on the bulb or the housing, confirm whether the headlights are halogen, HID, or LED, and match that designation. Position names that say “with halogen headlights” or “with LED headlights” are separate configurations.
