Replacement check
Read the number on the installed bulb or the housing. Confirm whether the headlights are halogen, HID, or an LED assembly. H11 and H11B are different. 9005 and 9006 are different. This page does not substitute a nearby designation to fill the product list.
Questions
What fog light bulb does the Chevrolet Cobalt use?
2010 stores H11 LED, H16 LED for fog lights.
What turn-signal bulb does the Chevrolet Cobalt use?
Halogen-configuration turn signals in 2010 store 3457A, 3157, 37. An LED-headlight configuration can list LED instead of these bulbs.
What brake-light bulb does the Chevrolet Cobalt use?
Halogen-configuration brake lights in 2010 store 3157R.
What does an LED record mean?
A stored part of LED means that configuration is recorded as an LED assembly. It is not a replaceable halogen bulb, and this page does not sell an LED conversion as the OEM bulb for that assembly.
Can I substitute a nearby bulb number?
No. H11 and H11B stay different. 9005 and 9006 stay different. This page matches the stored designation and does not swap in another bulb to fill the product list.
Does a catalog match guarantee the bulb fits?
A designation match means the product is filed under that bulb number and technology. It does not prove the lamp, socket, or vehicle configuration. Check the bulb in the housing before ordering.
How do I verify the replacement?
Read the number on the bulb or the housing, confirm whether the headlights are halogen, HID, or LED, and match that designation. Position names that say “with halogen headlights” or “with LED headlights” are separate configurations.
Does the Chevrolet Cobalt bulb chart change by year?
Bulb rows are stored for 6 years, 2005–2010. This page shows 2010. Choose another year to see that chart. Years are not collapsed into one bulb list.
