Buick Regal 2013 Bulb Size
Bulb size chart
This 2013 Buick Regal bulb size guide helps you verify the correct bulb for each lighting position on the car. Whether you are replacing an exterior lamp, an interior bulb, or a headlight component, the page organizes the fitment by location so you can match the right size before you buy.
The 2013 Buick Regal was offered with different lighting setups depending on trim, package, and market, so the bulb used in one version may not be the same in another. Use the position-specific listings here to narrow down the correct bulb size for the headlight, fog light, turn signal, brake light, dome light, and other lamps on your Regal.
For best fitment, always compare the bulb chart with the lighting equipment actually installed on your car. Halogen and HID headlight packages use different bulbs, and some exterior positions may change with trim or optional lighting packages. If you are considering LED replacements or other aftermarket conversions, make sure the bulb base, shape, and electrical compatibility are correct for the housing. It is also smart to remove the old bulb and check the number printed on it before ordering, especially on vehicles that may have been modified or serviced with non-original parts.
