Chevrolet Equinox 2018 Bulb Size
Bulb size chart
This 2018 Chevrolet Equinox bulb size guide helps you verify the correct bulb by lighting position, so you can match the right part before you buy. Because the Equinox could be equipped with different headlight and rear lamp setups, the bulb list is organized by function rather than by a single universal part number.
Use this page to check the bulb size for headlights, brake lights, turn signals, parking lights, reverse lights, interior lights, and license plate lights. That makes it easier to confirm fitment for your specific 2018 Equinox, whether it has halogen, HID, or LED lighting equipment.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb position on your vehicle with the chart before ordering. The 2018 Equinox uses different bulb types depending on whether it has halogen, HID, or LED headlights, and some rear lamp functions also change with the lighting package. If you are converting to aftermarket LEDs, check polarity, bulb depth, and whether the housing is designed for a standard filament bulb. The safest approach is to inspect the installed bulb first and match the base and size exactly before purchase.
