Chevrolet Traverse 2018 Bulb Size
Bulb size chart
This page for the 2018 Chevrolet Traverse helps you verify bulb sizes by lighting position, so you can match the right replacement to the right socket. Whether you are replacing a headlight, tail light, reverse light, or interior lamp, checking the bulb location first is the easiest way to avoid ordering the wrong part.
The Traverse uses a mix of LED lighting and traditional bulb types depending on the position, and some applications may vary by trim or market. Use the bulb chart on this page as a position-by-position guide for the 2018 Chevrolet Traverse before you buy replacements or plan an upgrade.
Fitment can differ between trims, lighting packages, and body styles, so it is smart to confirm what is actually installed on your vehicle before ordering. Some positions on the 2018 Traverse are listed as LED, while others use standard bulb sizes, and some headlight setups may differ between halogen-style and HID or LED-equipped versions. If you are considering aftermarket LED conversions, make sure the bulb base, polarity, and housing depth are compatible, since not every reflector or projector assembly works well with a retrofit. The safest approach is to inspect the existing bulb or compare the vehicle’s original equipment before purchase, especially for front lighting, fog lights, and any optional equipment.
