Buick Regal Bulb Sizes
2017 Buick Regal stores 27 bulb-chart rows across 21 lighting positions. LED headlight equipment is stored as its own configuration, not as an extra bulb in the halogen lamps.
Stored halogen, HID, Bi-LED, and LED rows are alternative equipment when the chart lists more than one. A vehicle uses one lighting system. Verify the lamps installed before ordering. A halogen bulb is not the replacement for an LED assembly, and an LED conversion is not shown as the OEM halogen bulb.

Replacement check
Read the number on the installed bulb or the housing. Confirm whether the headlights are halogen, HID, or an LED assembly. H11 and H11B are different. 9005 and 9006 are different. This page does not substitute a nearby designation to fill the product list.
Year variations
- Halogen low beam stays H11 across the stored years.
Questions
Does the 2017 Buick Regal chart include fog lights?
No fog-light bulb is stored for this year. This page does not add one.
What turn-signal bulb does the Buick Regal use?
Halogen-configuration turn signals in 2017 store 7440A, 7440. An LED-headlight configuration can list LED instead of these bulbs.
What brake-light bulb does the Buick Regal use?
Halogen-configuration brake lights in 2017 store LED.
Does the Buick Regal have both halogen and LED headlights?
The chart stores halogen-headlight positions and LED-headlight positions as alternative equipment. A single truck uses one of those systems. Verify the lamps on the vehicle before ordering.
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.
How are HID bulbs handled?
D-series capsules such as D1S or D3S are HID. Exact catalog matches for those positions use HID products, not halogen bulbs.
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.
Does the Buick Regal bulb chart change by year?
Bulb rows are stored for 13 years, 1999–2017. This page shows 2017. Choose another year to see that chart. Years are not collapsed into one bulb list.
