Lochnchn Tail Light for GMC Sierra 2019–2025 (Halogen) — Direct-Fit Weather-Resistant Rear Lamp

Lochnchn replacement tail light designed for halogen-equipped GMC Sierra models from 2019 through 2024, offering a durable, waterproof rear lamp with brake, reverse, and running light functions.

If your Sierra’s original halogen tail lamp needs replacing, this Lochnchn unit is built to match the factory halogen systems on many 2019–2024 Sierra 1500 trims and 2019–2024/2025 heavy-duty models. It is intended as a direct-fit replacement for non-LED tail light assemblies and is molded from weather-resistant plastic to withstand road conditions while restoring rear lighting performance.

Which GMC Sierra years and trims will this Lochnchn tail light fit?

This assembly is compatible with factory halogen tail lights on a wide range of Sierra trucks. It fits 2019–2024 Sierra 1500 trims such as Pro, SLE, and Elevation, plus 2019–2025 Sierra 2500HD and 3500HD, and the 2022 Sierra 1500 Limited. It will not fit models that came from the factory with full LED tail light assemblies.

• Fits halogen-equipped Sierra 1500 (Pro, SLE, Elevation) 2019–2024

How does this tail light perform in everyday driving and weather?

The housing is crafted from durable plastic with seals engineered to resist water and dust intrusion, helping maintain brightness and functionality over time. The unit supports three standard bulb-driven modes — stop (brake), reverse, and running — when used with the original halogen bulbs.

• Weather-resistant plastic construction for longevity
• Sealed against moisture and debris to protect internal components
• Supports brake, reverse, and driving light functions with halogen bulbs
• High-brightness finish to restore rear visibility

Is installation difficult and what should I prepare?

The tail light is designed to align with the stock mounting points for a straightforward replacement on compatible vehicles. Basic hand tools typically suffice for do-it-yourself installation, but professional installation is recommended if you’re not comfortable working on vehicle electrical or body components.

• Direct-fit design for factory mounting locations
• Requires compatible halogen bulb sockets—no LED conversion included
• Basic tools needed: screwdriver, trim removal tools, and gloves
• Professional install advised if unsure about electrical connections

What should I check before ordering to ensure correct fit?

Verify your truck’s model year and whether your OEM tail lights are halogen or full LED; this Lochnchn unit is for halogen configurations only. Also confirm left/right placement and compare mounting points or connector types with your existing assembly to avoid returns or fitment issues.

• Confirm year, model, and trim of your GMC Sierra
• Check that the current tail light is halogen, not factory LED
• Compare connector type and mounting tabs with your present lamp
• Contact support if you need help identifying fitment before purchase

Who is this for? This Lochnchn tail light suits Sierra owners who need a reliable, weatherproof halogen replacement to restore factory-style rear lighting on compatible 2019–2025 models. It’s ideal for do-it-yourself mechanics comfortable with basic vehicle electrical work, and for service shops seeking a cost-effective direct-fit assembly for halogen-equipped GMC Sierra 1500, 2500HD, and 3500HD trucks.
