Chevrolet TrailBlazer 2009 Bulb Size
Bulb size chart
This page covers bulb sizes for the 2009 Chevrolet TrailBlazer and is organized by lighting position so you can quickly verify the correct fit before ordering. Whether you are replacing an exterior lamp or a small interior bulb, checking the bulb chart by location helps reduce guesswork and makes replacement faster.
The 2009 TrailBlazer uses several different bulb types depending on the light assembly, and some positions may vary by trim, market, or body style. Use this guide to match the bulb to the exact location on your vehicle, such as headlights, tail lights, license plate lights, dome lights, and fog lights.
For the best fit, compare your TrailBlazer’s trim and lighting package with the bulb chart before buying. Some positions may use halogen bulbs from the factory, while others may be converted to LED by a previous owner, so it is smart to inspect the installed bulb first. Aftermarket LED upgrades can work well, but beam pattern, polarity, and housing compatibility may differ from stock halogen bulbs. If a light has been changed before, the bulb currently in the vehicle is often the most reliable reference for replacement.
