Goopool GMC Yukon Left Tail Light Replacement 2015-2020 — Plug-and-Play OEM Fit, Bulb & Harness Included

Goopool's left rear tail light is a direct-fit replacement for GMC Yukon and Yukon XL models from 2015 through 2020, restoring factory appearance and lighting function.

If your Yukon’s left taillight is cracked, fogged, or no longer performing, this Goopool assembly provides a straightforward, OEM-style substitute engineered for the same fit and mounting points as the original. Built from durable materials and supplied with the bulb and wiring harness, it’s designed for plug-and-play installation so you can get back on the road quickly while maintaining the vehicle’s exterior look and safety illumination.

Which Yukon years and submodels will this left taillight fit?

This tail light is compatible with Yukon and Yukon XL vehicles across 2015–2020 model years. It covers common trim levels and matches the left (driver) side mounting and electrical connections used by the factory assembly.

• Fits Yukon and Yukon XL 2019–2020 and 2015–2018 model ranges
• Compatible with Denali, SLE, and SLT submodels
• Direct replacement for the left/driver side assembly

Does it replace the original part numbers my vehicle lists?

Yes — the Goopool unit replaces the factory taillight part numbers associated with compatible Yukon models. That makes ordering and cross-referencing easier when you’re matching what was removed or listed in vehicle documentation.

• Replaces OEM numbers: 84536242 and 23380459
• Also cross-references to GM2800268 for compatibility
• Designed to match original mounting points and connectors

What are the durability and weather protection features?

The assembly is manufactured from quality plastics and sealed components to resist common environmental stresses. Goopool tests these units for water intrusion and dust resistance so the light remains functional through normal road exposure.

• Sealed housing to reduce fogging and water ingress
• UV-resistant materials to limit sun-related discoloration
• Engineered for shock resistance and corrosion protection

How difficult is installation and what comes in the box?

Installation is intended to be simple for someone with basic vehicle maintenance experience — the light comes with the bulb and wiring harness and connects directly to the factory socket. No complex modifications or cutting are required for a correct fit on supported Yukons.

• Includes taillight assembly, bulb, and wiring harness
• Plug-and-play connection to existing vehicle wiring
• Mounting points match factory locations for straightforward installation

Who this is for: This Goopool left taillight suits Yukon and Yukon XL owners who need a reliable, cost-effective replacement that closely matches factory appearance and fit. It’s ideal for drivers repairing damage from road debris, replacing fogged or leaking lenses, or restoring a vehicle before sale — especially if you own a Denali, SLE, or SLT model from 2015–2020 and want a direct, tested replacement without extensive modification.
