Chevrolet Impala 2008 Bulb Size
Bulb size chart
This page for the 2008 Chevrolet Impala helps you verify bulb sizes by lighting position, so you can match the correct replacement to the exact lamp on the car. Whether you are replacing a burned-out exterior bulb or updating an interior light, using the right socket and bulb type saves time and avoids fitment problems.
The 2008 Impala uses a mix of halogen, incandescent, and LED lighting depending on the location and equipment level. Because trim and lighting package can vary by market and body style, it is smart to confirm the bulb chart for the specific light you are servicing before you buy replacements.
For best results, compare the installed bulb to the listing before ordering, especially on positions that may differ by trim or package. Some owners choose LED upgrades for brighter light or longer life, but an aftermarket conversion may change beam pattern, color, or warning behavior if the vehicle was designed for halogen or incandescent bulbs. That matters most on headlights, fog lights, and exterior signal lamps. If you are unsure, remove the old bulb and check the base style and markings first, then match it to the chart on this page. This is the safest way to avoid buying the wrong part for your 2008 Chevrolet Impala.
