Bulb size chart
9005 Bulbs
Used for: Headlight Bulb High Beam
H11 Bulbs
Used for: Headlight Bulb Low Beam
The 2015 Chevrolet Colorado uses different headlight bulb sizes depending on the lighting position, and this page is designed to help you verify the correct bulb by location. For this model year, the listed headlight bulbs are 9005 for the high beam and H11 for the low beam, making it easier to match the right bulb before you buy.
Because trim level, market, and lighting package can affect fitment, it is smart to confirm the bulb type for your specific 2015 Colorado before replacing anything. Using the correct bulb size helps ensure proper beam pattern, safer night driving, and a smoother installation process.
If your Colorado has been modified or equipped with a different headlight setup, fitment may vary from the standard listing. This is especially important when comparing halogen bulbs to LED replacements or when considering aftermarket conversion kits, since some upgrades may require extra adapters, resistors, or housings to work correctly. Before ordering, check the bulb already installed in your truck and compare it with the bulb chart on this page. That quick check can save time, prevent returns, and help you avoid buying a bulb that does not match your trim or lighting package.

Can I use LED bulbs instead of halogen bulbs in my 2015 Colorado?
Yes, many owners choose LED replacements, but fitment and performance can vary. Some LED bulbs may need additional parts or may not produce the same beam pattern as halogen bulbs.
Why should I check the installed bulb before ordering a replacement?

If the bulb in your vehicle does not match the chart, use the installed bulb as the final reference and check whether your truck has a different trim, package, or aftermarket lighting setup.

Use the correct bulb size for the specific beam position, handle the new bulb carefully, and confirm that it is seated properly before driving at night.
