Bulb size chart
This 2012 Chevrolet Traverse bulb size guide is designed to help you verify the correct bulbs by lighting position before you buy replacements. Whether you are changing a headlight, a cabin bulb, or an exterior signal lamp, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
The Traverse uses different bulb types across the front, rear, and interior lighting areas, so the same vehicle can require several sizes. This page organizes the most common bulb positions for the 2012 Chevrolet Traverse and makes it easier to compare your existing bulbs with the listed fitment.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm what is installed in your vehicle before ordering. Some positions may use halogen bulbs from the factory, while others may be upgraded to LED or replaced with aftermarket LED conversions later. If your Traverse has been modified, the bulb listed here may not match what is currently in the housing. For the best results, inspect the old bulb, check the base style, and compare the connector and socket shape before purchase.
