2018-2024 Equinox Headlight Guide: Decoding Halogen, HID, and LED Variations

Headlight Variations: 2018-2024 Chevrolet Equinox

The third-generation Chevrolet Equinox underwent a significant facelift for the 2022 model year, which included major changes to the front fascia and headlight design. This creates a clear split in compatibility. Understanding which version your vehicle has is the most important step in buying a replacement.

Pre-Facelift: 2018-2021 Equinox

During these years, Chevrolet offered three primary headlight types that are not interchangeable. Installing the wrong type will result in connection errors, features not working, and potential electrical issues.

• Halogen: Found on lower trim levels, these assemblies use a single, replaceable 9012 halogen bulb for both low and high beams in a projector housing. They typically have a simple chrome reflector interior and may have an incandescent or basic LED daytime running light.
• HID/Xenon: Available on higher trims like the Premier, these headlights use a High-Intensity Discharge (HID) bulb (type D5S) for a brighter, whiter light output. They also feature a distinct LED daytime running light strip. These assemblies require a ballast (igniter) to operate, which is often included with the assembly.

• Full LED (Less Common): Some top-tier 2018-2021 models were equipped with full LED headlights, where the light source is a non-serviceable LED module. These are distinct from the more common HID units.

Post-Facelift: 2022-2024 Equinox

The 2022 refresh introduced a slimmer, more modern headlight design and shifted entirely to LED technology, but with key differences between trim levels. Halogen and HID options were discontinued.

• Standard LED: Found on LS and LT trims, these are full LED assemblies with LED low and high beams. The provided OEM part numbers 85538061 and its successor 86517973 correspond to the right-hand (passenger side) standard LED headlamp for 2022-2024 LS models.
• Premier LED: The Premier trim features a different, more advanced projector-style full LED headlamp with unique styling. These are not interchangeable with the standard LED units found on LS, LT, and RS trims.

Symptoms of a Failing Headlight Assembly

• Dim or Flickering Light: On HID models, this often points to a failing bulb or ballast. On LED models, it indicates a failing internal driver or LED module, which requires replacing the entire assembly.
• Moisture or Condensation Inside: Fine mist or fogging that appears and disappears with weather changes can be normal. However, large water droplets, pooling water at the bottom, or persistent condensation that never clears indicates a seal failure. This will lead to corrosion and premature failure of bulbs and electronics. GM has issued technical service bulletins (TSBs) explaining that some condensation is normal, but also provides a fix for excessive moisture involving a replacement access cover with a desiccant pack (Part No. 42715667).
• Yellowing or Hazy Lens: UV radiation from the sun degrades the protective outer coating of the plastic lens, causing it to become yellow and cloudy. This significantly reduces light output and can be a safety hazard.
• One or More Functions Inoperative: If the low beam, high beam, or turn signal stops working, the issue could be a bulb (on Halogen/HID models) or a failure within the sealed LED unit. Always check fuses first, but if a function on an LED assembly fails, the entire unit usually needs replacement.
• Cracked Lens or Housing: Physical damage from impacts not only looks bad but breaks the weather seal, guaranteeing moisture will enter and destroy the internal components.

Buying a Used Headlight Assembly: What to Look For

A recycled OEM headlight is often the best value, providing factory quality and fit at a lower price. However, you must inspect it carefully.

1. Confirm the Year Range and Type: First, determine if you need a 2018-2021 or 2022-2024 assembly. Then, identify if your original is Halogen, HID, or LED. Look for markings on the lens or stickers on the housing. When in doubt, match the OEM part number from your old headlight to the new one.
2. Inspect All Mounting Tabs: The plastic mounting tabs are brittle and often break during removal or minor impacts. A used headlight with one broken or professionally repaired tab might be acceptable, but multiple broken tabs will cause fitment issues and vibration.
3. Check the Lens Condition: Look for deep scratches, rock chips, and internal 'crazing' (fine spiderweb cracks). Minor external hazing can be polished, but a lens that is cracked or crazed from UV damage cannot be saved.
4. Examine the Seal: Look at the channel where the lens meets the black plastic housing. If the butyl rubber sealant looks messy, gouged, or uneven, it's a red flag that the headlight may have been opened, possibly for a shoddy repair. This dramatically increases the risk of future moisture leaks.
5. Look for Included Components: For HID models, check if the ballast and bulb are included. For all types, see if the bulb access covers are present and if any wiring pigtails are intact. LED assemblies are typically sold as a complete, sealed unit.

Replacement and Alignment

Replacing the headlight assembly on a 2018-2024 Equinox is a moderately difficult job for a DIYer, primarily because it requires removing the front bumper cover to access the mounting bolts.

Procedure Overview:

1. Disconnect the negative battery terminal.
2. Remove the plastic clips and screws holding the top of the bumper cover in the engine bay.
3. Remove the screws in each wheel well that attach the bumper cover to the fender.
4. Carefully unsnap the bumper cover from the retaining brackets below the headlights and pull it forward. You do not need to remove it completely, but you need enough clearance to work.
5. Unbolt the headlight assembly (typically three or four 10mm bolts).
6. Disconnect the main electrical connector and remove the assembly from the vehicle.
7. Installation is the reverse of removal.
