FAQ

How can I confirm the replacement tail light fits my Cadillac XT4 or CT5?

Check your vehicle's model year, installation side, and original part number. For example, the 2019–2021 Cadillac XT4 left LED tail light replaces OE 84522856, while the 2020–2025 CT5 uses different assemblies. XT4 and CT5 tail lights are not interchangeable.

Are Cadillac LED tail lights sold individually or as a pair?

Both options are available for the 2020–2025 Cadillac CT5, including separate driver-side and passenger-side lights and a complete left-and-right pair. The 2019–2021 XT4 listing is for the left side only. Check the product title and package contents before ordering.

Can I replace my Cadillac LED tail light without modifying the vehicle?

G-PLUS Cadillac LED tail lights are designed as replacements for the specified factory assemblies. Before installation, verify the OE number, electrical connector, and mounting points. Installation instructions are included. After replacement, test the tail lights, brake lights, and turn signals to confirm proper operation.
