Chevrolet Cobalt 2006 Bulb Size
Bulb size chart
This page covers bulb sizes for the 2006 Chevrolet Cobalt and helps you verify the correct bulb by lighting position. Whether you are replacing a burned-out exterior lamp or updating an interior light, matching the bulb to the right location is the easiest way to avoid fitment mistakes.
The 2006 Chevrolet Cobalt uses different bulb types for the headlights, tail lamps, markers, and cabin lights. Because trim level, lighting package, body style, and market can change the setup, it is smart to compare the bulb chart with the bulb already installed in your car before you buy replacements.
For best results, confirm whether your Cobalt uses halogen or an LED conversion in any given position, since aftermarket upgrades can change the bulb style or required adapter. Trim and package differences may affect fog lights, interior lamps, and some rear lighting functions, so the same year and model can still have different fitments. If you are switching to LED bulbs, make sure the replacement is designed for the same socket and can work with your vehicle’s electrical system. When possible, remove the old bulb and check the number printed on the base before ordering, especially for exterior lights and any bulb that may have been changed previously.
