Lochnchn Right Rear Tail Light for GMC Sierra 2019-2025 (Halogen) — Direct-Fit, Waterproof Replacement

Lochnchn replacement right rear tail light designed for 2019–2025 GMC Sierra models (halogen versions only) — a durable, waterproof plastic assembly that restores brake, reverse and driving illumination.

If your GMC Sierra’s factory halogen tail lamp is cracked, faded, or otherwise underperforming, this Lochnchn right-side tail light is built to be a direct-fit replacement for many Sierra pickups across model years. It’s manufactured from resilient plastic, sealed against water and dust, and intended for vehicles equipped with halogen (non-fully-LED) tail light systems. Before ordering, confirm your truck’s year and whether the original lamp is halogen rather than full LED.

Which Sierra years and trims will this tail light fit?

This Lochnchn unit fits a broad range of GMC Sierra models produced from 2019 through 2025. Compatible trims include Sierra 1500 PRO/SLE/Elevation, Sierra 2500HD, Sierra 3500HD, and the 2022 Sierra 1500 Limited, provided the vehicle uses factory halogen tail lamps.

• Compatible model years: 2019–2025 (including 2022 limited)
• Works with Sierra 1500 PRO, SLE, Elevation trims
• Also fits 2500HD and 3500HD heavy-duty models
• Not compatible with full LED factory tail light assemblies

How does the light perform and what modes does it offer?

The replacement lamp supports the same basic lighting functions as the original halogen assembly: brake illumination, reverse lighting, and the running/driving light. When the correct halogen bulb is installed, the unit cycles through those three modes to match normal vehicle signaling and visibility requirements.

• Three lighting modes: brake, reverse, driving (running light)
• Uses standard halogen bulb sockets — confirm bulb type before installation
• Bright, focused output engineered to meet everyday road visibility
• Sealed design preserves bulb life by keeping out moisture and debris

What are the build quality and durability features?

The housing is molded from sturdy plastic and sealed to resist water and dust intrusion, helping prolong service life in wet or dirty conditions. The surface finish is designed to match factory aesthetics so the replacement looks consistent with the truck’s original styling.

• Durable plastic construction with waterproof and dustproof sealing
• High-brightness lens and reflector layout for clear signaling
• Stress-tested fit points for reliable alignment with factory mounts
• Surface finish intended to visually match OEM appearance

Is installation difficult and what should I prepare?

Many owners can perform a direct swap using basic hand tools since the tail light is made to align with factory mounting points and connectors for halogen systems. Professional installation is recommended if you’re unsure about electrical connectors or need to transfer bulbs from the old assembly.

• Direct-fit design for easier replacement of OEM halogen units
• Requires basic tools; bulb transfer may be necessary
• Professional installation advised for electrical or fitment concerns
• Confirm vehicle year and halogen vs. LED system before ordering

Who this is for: This Lochnchn right rear tail light suits GMC Sierra owners who need a halogen-compatible replacement for 2019–2025 1500 (PRO/SLE/Elevation), 2500HD, or 3500HD models, and for drivers who want a reliable, sealed lamp that restores original signaling functions without modifying the vehicle’s lighting system. If your truck originally came with full LED tail lights, choose an LED-specific replacement instead.
