Do these need any wiring harness adapters or can I plug them straight in?

Plug-and-play compatibility depends on your specific trim and wiring configuration. Have your vehicle's OEM connector type on hand before ordering — this will let you confirm compatibility with our support team if needed.

Will these work if my vehicle has factory projector or reflector headlights?

These are projector-style units and mount at your factory headlight points. If your Equinox originally had reflector headlights, confirm the mounting bracket alignment with our support team to avoid fitment issues.

Do the DRL lights stay on when the headlights are off, or do they require a separate switch?

The DRL function is integrated into the assembly. Your vehicle's existing DRL control system activates them — no additional switch or relay is required.
