YzusGomumu Third Center High Mount Stop Light for 2015–2020 GMC Yukon & 2020 Escalade — LED, Plug-and-Play

YzusGomumu Third Center High Mount Stop Light is a direct-fit replacement third brake light engineered to restore center rear signaling for 2015–2020 GMC Yukon/Yukon XL and 2020 Cadillac Escalade models.

This high-mount stop lamp replaces the factory unit with a plug-and-play assembly designed to match original equipment fit and function. Built for higher brightness and extended life, the unit offers improved visibility in routine and emergency braking situations and is engineered with water-resistant and vibration-tolerant materials to handle typical road conditions. Before purchase, verify your vehicle’s model year and OE number to ensure exact compatibility.

How does this third brake light improve rear visibility?

The third brake light sits centered at the top rear of the vehicle, making brake activation more noticeable to drivers following behind. Because it provides a high, eye-level signal, it complements the left and right tail lamps to give earlier warning of deceleration. This added cue helps other drivers react sooner in congested or high-speed traffic.

• High brightness LED array for clear daytime and nighttime visibility
• Centered mounting increases line-of-sight for trailing drivers
• Consistent light output across the full lamp to avoid dark spots
