FOR GMC YUKON CADILLAC ESCALADE THIRD BRAKE LIGHT HIGH MOUNT STOP LAMP 2015-2020

Third Brake Light High Mount Stop Lamp for GMC Yukon and Cadillac Escalade

This high mount stop lamp replaces the third brake light on GMC Yukon and Cadillac Escalade SUVs from 2015 through 2020, restoring the rear center brake signal.

Overview

This third brake light serves as the high mount stop lamp for GMC Yukon and Cadillac Escalade models built between 2015 and 2020. It sits above the rear window line and lights when the brakes are applied so following traffic sees the stop signal from farther back. It suits owners replacing a cracked, water-filled, or failed factory lamp.

Specs At A Glance

Good To Know

Q: Will this high mount stop lamp plug into my existing wiring? A: It is designed to connect to the factory brake light circuit on the listed 2015-2020 models. Check the connector on your original lamp before ordering, as trim levels can vary.

Q: Why does my third brake light collect water? A: The high mount position sees direct rain and wash spray, and aging gaskets let moisture past the seal. Replacing the lamp assembly restores both the seal and the brake signal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
