Chevrolet Traverse 2020 Bulb Size
Bulb size chart
This page for the 2020 Chevrolet Traverse helps you verify bulb sizes by lighting position, so you can match the correct replacement before you buy. Because exterior and interior lamps can differ by trim, package, and market, it is best to check the exact light location on your vehicle rather than relying on a single all-around bulb size.
For the 2020 Traverse, many lighting functions use LED assemblies, while a few serviceable positions still use replaceable bulbs such as the back up reverse light, license plate light, cargo light, front turn signal, and parking light. Use the chart on this page to narrow down the correct bulb by function, then confirm the installed bulb if your vehicle has been modified or equipped differently.
Fitment can vary on the 2020 Chevrolet Traverse depending on trim level, lighting package, body style, and market, so the same model year may not use the same bulb in every position. Some lamps are LED from the factory, while others may be halogen or use a specific bulb type such as 921, 7444NA, 2825/98, 194NA, 6612F, or 2504 LED. If your Traverse has been converted to aftermarket LED bulbs or has had a headlamp assembly replaced, always compare the installed bulb, connector, and housing design before ordering. This is especially important for headlight and fog light conversions, where beam pattern, polarity, and fitment can affect performance and legality.
