The 2019 Chevy Colorado primarily uses standard halogen headlights with H11 bulbs for the low beams, 9005 bulbs for the high beams, and H11 bulbs for fog lights on most models. Always verify for your specific trim, as factory options can vary.
Standard headlight bulb types
The following lists the commonly installed bulb sizes for the 2019 Colorado’s factory headlight assemblies.
- Low beam headlight: H11
- High beam headlight: 9005 (HB3)
- Fog lights (if equipped): H11
These bulb types cover the majority of 2019 Colorado models, making it straightforward to purchase replacements without guesswork.
Variations by trim and aftermarket considerations
There can be variations based on trim level or optional equipment, and some owners opt for upgrades after purchase. It’s important to confirm the exact bulb type for your specific vehicle configuration.
- Some trims or aftermarket headlight assemblies may use different configurations or upgrade options (such as projector-style headlights or LED daytime running lights) but bulb replacement for the stock low/high beams typically remains H11 and 9005 on most early 2019 Colorado models.
- If converting to HID/LED or installing aftermarket headlights, you may need wiring adapters, ballast, or CAN-BUS decoders to avoid flickering or warning messages, and you should ensure proper alignment and beam pattern.
When in doubt, consult the owner’s manual or inspect the bulb socket in person to verify the exact bulb type before purchasing replacements.
How to replace headlights safely
Before starting, ensure the vehicle is off, the keys are removed, and the engine is cool. Access the headlight compartment from the back of the headlight housing, unplug the bulb connector, twist or unlock the bulb socket, remove the old bulb, and install the new one in reverse order. Reconnect the harness, secure any caps, and test the lights at night or with a duty cycle check to confirm proper operation and alignment.
Summary
In brief, a 2019 Chevy Colorado uses H11 low beams, 9005 high beams, and H11 for fog lights on most stock configurations. Verify the exact bulb type for your trim and consider aftermarket options or upgrades carefully, keeping in mind the potential need for adapters or alignment when making changes.
