The 2010 Chevy Cobalt typically uses H11 bulbs for the low-beam headlights and 9005 bulbs for the high beams. This pairing covers the two main forward-facing headlight functions on most U.S.-spec Cobalts from that year.
In this article, we’ll break down what each bulb does, how to verify the correct bulb for your specific car, and tips for replacement. If your Cobalt is a different trim or has optional fog lights, the bulb setup can vary, but the main headlights typically follow the H11/9005 standard.
Bulb types for the 2010 Chevy Cobalt
The front headlights consist of two separate functions with distinct bulb types. The standard configuration uses a single bulb for each function along the assembly.
- Low beam (dipped/standard headlight): H11
- High beam (main headlight): 9005
Always confirm by checking the bulb currently in the housing or the owner's manual, as some market-specific or trim variations can differ.
Replacement and verification tips
To replace the bulbs, you’ll typically access the headlight from the engine bay, remove the power connector and the retaining cap, then twist and pull the bulb out. When installing, handle bulbs with gloves or a clean cloth to avoid oils on the glass, which can shorten bulb life.
- Open the hood and locate the back of the headlight assembly.
- Remove the dust cap and unplug the electrical connector.
- Twist the bulb counterclockwise to release it from the housing and pull it out.
- Insert the new bulb (H11 for low beam, 9005 for high beam) and twist clockwise to lock.
- Reconnect the wiring, reseal with the dust cap, and test the headlights.
If you’re unsure of your exact trim or have trouble seating the bulb, consult the vehicle's manual or contact a dealership or auto parts professional for confirmation.
Summary
For a 2010 Chevy Cobalt, expect H11 low-beam bulbs and 9005 high-beam bulbs in the primary headlight assemblies. Verify with your manual or by inspecting the existing bulbs, and follow proper replacement precautions to ensure optimal performance and safety.
