OEM Cadillac Tail Lights and Components
Here you will find tail lamp assemblies, circuit boards, sockets and the LED units late models carry.
This page holds the Cadillac side of that catalog. Every part listed is a genuine OEM GM part under its current factory number, pulled from the same Cadillac catalog our parts counter runs on, never an aftermarket substitute.
How these parts fail on Cadillac vehicles
Tail lamps lead rear collision demand, and the LED assemblies fail in sections that only a complete factory unit restores.
What we ship most. For Cadillac owners, the heaviest traffic runs through our Cadillac CT5, Cadillac Escalade and Cadillac XT5 pages.
OEM versus aftermarket in this system
GM housings aim correctly, seal against moisture and carry the right connectors and ballast or driver spec. Aftermarket housings fog, flicker and fail inspection aim tests at a rate that makes the savings disappear.
Before you order. Lighting splits by trim and option content, with halogen, HID and LED versions of the same lamp carrying different part numbers. The VIN picks the right one. Include the VIN at checkout and fitment gets verified before the box is packed.
