Chevrolet Cobalt 2007 Bulb Size
Bulb size chart
This page helps you verify the bulb sizes for a 2007 Chevrolet Cobalt by lighting position, so you can match the right replacement to the right socket. Whether you are changing a headlight, tail light, interior lamp, or license plate light, checking the exact location first makes bulb shopping much easier.
The 2007 Chevrolet Cobalt uses several different bulb types depending on the lamp location, and some fitment can vary by trim, body style, and lighting package. Use the chart below to confirm the correct bulb size before you buy, especially if you are replacing more than one bulb at the same time.
For best results, compare the bulb in your car with the size listed on this page before ordering, since trim and package differences can change fitment. Halogen bulbs and LED replacements are not always direct swaps, even when they share the same base or shape, so make sure the new bulb is compatible with your housing and wiring. Aftermarket LED conversions for headlights or fog lights may also require extra parts or may not match the original beam pattern. If a bulb is burned out, checking the installed bulb number is the safest way to confirm the correct replacement before purchase.
