Chevrolet Cobalt 2010 Bulb Size
Bulb size chart
This 2010 Chevrolet Cobalt bulb size guide helps you verify the correct bulb by lighting position, so you can match the right part before you buy. Whether you are replacing a headlight, tail light, license plate lamp, or interior bulb, checking the location first is the easiest way to avoid a wrong-fit purchase.
The 2010 Cobalt uses different bulb types depending on the lamp housing and function. That means the same model year can use one bulb for the brake light, another for the rear turn signal, and different sizes for the dome, map, or trunk lights. This page organizes the common bulb positions to make replacement faster and more accurate.
Fitment can vary by trim, market, body style, and lighting package, so it is smart to confirm the installed bulb before ordering. Some positions may use standard halogen bulbs, while others may be upgraded to LED replacements or LED conversion kits. If you are switching from halogen to LED, check polarity, bulb depth, and whether the housing has enough space for the new bulb and heat sink. For the best results, compare the old bulb number and the socket shape before purchase, especially on exterior lights that may have been changed by a previous owner.
