2017 Chevrolet Equinox Bulb Size Guide

Quick reference

The 2017 Chevrolet Equinox largely utilizes halogen bulbs across its various lighting functions. While most trims will come equipped with standard halogen headlights (H11 for low beam, H9 for high beam), some premium trim levels might feature factory-installed HID (High-Intensity Discharge) projector headlights for the low beams, offering superior illumination. It's crucial to verify your specific vehicle's configuration before purchasing replacement bulbs, especially for the headlights.

LED vs Halogen Upgrade Considerations

Upgrading your 2017 Chevrolet Equinox from its factory halogen bulbs to LED replacements can significantly enhance visibility and modernize the vehicle's appearance. However, there are several factors to consider to ensure a smooth transition.

CANBUS Errors: Modern vehicles like the 2017 Equinox utilize a CANBUS (Controller Area Network Bus) system to monitor various electrical components, including lighting. Halogen bulbs draw more power than LEDs, and when an LED bulb is installed, the reduced power draw can trigger a "bulb out" warning light on your dashboard or cause hyper-flashing for turn signals. To prevent these CANBUS errors, you'll often need to install CANBUS-compatible LED bulbs or use load resistors in parallel with the LED bulbs. Load resistors trick the CANBUS system into thinking a standard halogen bulb is still in place by mimicking the electrical resistance.

Adapters Needed: For some installations, particularly for headlights, you might require specific adapters or mounting brackets to properly seat the LED bulbs into the housing, as their physical dimensions can differ from traditional halogens. Additionally, some LED bulbs have larger heatsinks, which might necessitate modifications to the dust caps or headlight housing to ensure proper fitment and ventilation.

Beam Pattern: When upgrading headlights to LED, pay close attention to the beam pattern. Poorly designed LED replacement bulbs can scatter light, creating glare for oncoming drivers and reducing your overall effective illumination. Opt for LED bulbs specifically designed to mimic the beam pattern of their halogen counterparts or choose reputable brands known for quality optics. Projector headlight housings generally work better with LED upgrades than reflector housings due to their more controlled light output.

How to Replace Each Bulb

Replacing bulbs on your 2017 Chevrolet Equinox is a relatively straightforward process for most locations, though some may require more effort.

• Low Beam/High Beam Headlight: Access to the headlight bulbs is typically from behind the headlight assembly within the engine bay. You may need to remove a dust cap, disconnect the electrical connector, and then twist or unclip the bulb from its housing. For HID systems, consider professional assistance due to high voltage.
• Fog Light: Access is generally from underneath the front bumper or by removing the inner fender liner. Disconnect the electrical connector and twist out the bulb.
• DRL/Front Turn Signal: These are usually integrated into the same housing as the headlight. Access is similar to the headlight bulbs.
• Rear Turn Signal/Brake Light/Tail Light: Access these bulbs from inside the trunk or tailgate, often by removing a trim panel or accessing a cover behind the light assembly. Disconnect the electrical connector and twist out the bulb.
• Reverse Light: Similar access to the rear turn signals, usually within the same tail light assembly.
• License Plate Light: Typically accessed by unscrewing small plastic lenses above the license plate on the tailgate.
• Side Marker (Front/Rear): Usually a twist-in bulb accessible from behind the fender liner (front) or inside the trunk/tailgate (rear).
• Dome Light (Rear): Gently pry down the lens cover with a plastic trim tool. The festoon bulb clips into place.
• Map Lights (Front): Gently pry down the lens covers near the rearview mirror. The wedge bulbs can be pulled straight out.

Always ensure the vehicle is turned off, and the lights are cool before attempting any bulb replacement. Wearing gloves is recommended to avoid transferring oils to new halogen bulbs, which can shorten their lifespan.

Common Lighting Issues for this Generation

Owners of the 2017 Chevrolet Equinox may encounter a few common lighting-related issues:

• Premature Halogen Bulb Burnout: While not exclusive to the Equinox, frequent replacement of halogen bulbs (especially headlights or DRLs) can be a nuisance. This can be exacerbated by vibrations, voltage fluctuations, or even touching the glass during installation. Upgrading to higher-quality aftermarket halogens or LEDs can mitigate this.
• DRL Malfunctions: Due to shared wiring with the front turn signals, issues with one can sometimes impact the other. A malfunctioning DRL might present as a dim light or not illuminating at all.
• Tail Light/Brake Light Outages: These are common wear items. Regularly check your tail lights and brake lights, as a burnt-out bulb can lead to safety hazards and traffic citations.
• Corrosion in Sockets: Over time, moisture and road salt can lead to corrosion in bulb sockets, causing intermittent operation or complete failure. Cleaning the contacts with electrical contact cleaner and a small brush can often resolve this.

If you experience persistent lighting issues or are uncomfortable performing replacements yourself, it's always best to consult with a qualified technician.
