Chevrolet Colorado 2011 Bulb Size
Bulb size chart
The 2011 Chevrolet Colorado uses different bulbs depending on the lighting position, so it is important to match the bulb to the correct socket before buying replacements. This page is designed to help you verify bulb sizes by position, making it easier to identify the right fit for the headlight high beam and front fog light applications on your truck.
For the 2011 Chevrolet Colorado, the available bulb chart on this page lists the high beam headlight bulb as 9005 and the front fog light bulb as 9045. Because trim level, lighting package, body style, and market can change the exact setup, checking the bulb position on your specific vehicle is the safest way to confirm fitment.
Fitment can vary on the 2011 Chevrolet Colorado, especially between trims and factory lighting packages, so it is smart to compare the bulb currently installed in your truck with the chart before ordering. If you are switching from halogen to LED, make sure the replacement is designed for the same socket and has enough clearance inside the housing. Some aftermarket conversions may also need additional parts or adjustments to work properly, and bulb appearance can differ even when the base size is correct. Checking the installed bulb first is the best way to avoid returns and ensure the new bulb matches your vehicle.
