Chevrolet Impala 2011 Bulb Size
Bulb size chart
This page helps you verify the correct bulb sizes for the 2011 Chevrolet Impala by lighting position, so you can replace only the bulb you need instead of guessing by appearance. Whether you are changing a headlight, interior lamp, or rear signal bulb, matching the socket and location is the safest way to get the right fit.
The 2011 Chevrolet Impala uses a mix of halogen bulbs and small interior bulbs, and some positions may differ depending on trim, market, or lighting package. Use the bulb chart on this page as a guide for common fitments, and always confirm the exact lamp location before ordering replacements.
For best results, compare the installed bulb to the chart before buying, especially if your Impala has been modified or if the car uses a different trim or package than expected. Some owners upgrade halogen bulbs to LED for brighter output, but aftermarket LED conversions can affect beam pattern, glare, and warning behavior if the housing was designed for halogen. Fog lights and other exterior lamps may also have more than one compatible LED option, so check the socket style and physical clearance carefully. If you are replacing a burned-out bulb, removing the old bulb first is the easiest way to confirm the correct match.
