Bulb size chart
This page helps you find the correct bulb sizes for the 2010 Chevrolet Impala by lighting position, so you can match the right bulb to the right socket before you buy. Whether you are replacing a burned-out lamp or upgrading a few exterior lights, checking the bulb chart by location is the easiest way to avoid ordering the wrong part.
The 2010 Chevrolet Impala uses a mix of halogen, incandescent, and LED lighting depending on the lamp position. Common fitments on this model include H11 low beam bulbs, H9 high beam bulbs, 4157NA front turn signal and parking light bulbs, 3057R rear brake and tail light bulbs, and several interior bulbs such as 578, 194/7441, 912, and 37.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb in your vehicle before purchasing. Some owners choose LED replacements for brighter output or longer life, but an aftermarket LED conversion may change beam pattern, trigger warnings, or require additional parts depending on the socket and housing. If you are unsure, remove the installed bulb and verify the base style and markings before ordering, especially for fog lights, reverse lights, and interior lamps where multiple options may appear similar.
