Bulb size chart
This page helps you verify bulb sizes for the 2004 Chevrolet Impala by lighting position, so you can match the correct bulb before you buy. Whether you are replacing a headlight, a map light, or a trunk lamp, checking the bulb chart by location is the easiest way to avoid ordering the wrong part.
The 2004 Chevrolet Impala uses a mix of exterior and interior bulb types, and some positions may vary by trim, market, or lighting package. Use the bulb list on this page as a practical reference for common fitments such as the 9005 high beam, 3057R brake and tail light bulbs, 3457A front turn signal and parking bulbs, and several interior 194/7441 applications.
For the best fitment results, always compare the chart with the bulb already installed in your vehicle before purchasing, especially if your Impala has been modified or equipped with an aftermarket lighting setup. Trim and package differences can change the exact bulb used in certain positions, and some owners may find LED replacements or conversion kits where the factory bulb was halogen. If you are switching to LED, make sure the replacement is compatible with the socket, polarity, and available space, since some housings need additional clearance or resistors to work properly.
