Buick Regal 2014 Bulb Size
Bulb size chart
This 2014 Buick Regal bulb size guide helps you verify the correct bulbs by lighting position, so you can replace the right part the first time. Because trim and lighting equipment can vary, the bulb type may differ between halogen and HID headlight setups, and some exterior lights use LED units instead of replaceable bulbs.
Use this page as a quick reference for common exterior and interior bulbs on the 2014 Buick Regal. Whether you are changing a reverse light, license plate light, dome light, or headlight bulb, matching the bulb size to the correct location is the best way to avoid fitment mistakes and unnecessary returns.
Before buying, confirm your Regal’s trim, lighting package, body style, and headlight type, since those details can change the bulb list. The 2014 Regal may use halogen or HID headlamps, and the correct parking light or daytime running light bulb depends on that setup. If you are considering an aftermarket LED conversion, make sure the bulb base, physical length, and beam pattern are suitable for the housing, and check for possible warning messages or compatibility issues. The safest approach is to inspect the installed bulb before ordering, especially for interior lights and rear exterior lamps where previous repairs or market-specific equipment may have changed the original part.
