Tresound Tail Light Set for Chevy Silverado & GMC Sierra Fleetside 1988–1999 — Plug-and-Play ABS 3rd Brake Light

Complete replacement tail light set with an integrated third brake light designed to fit Fleetside (not Stepside) classic Chevy Silverado, GMC Sierra and compatible GM trucks from the late 1980s through 1999.

If you're restoring a classic GM pickup or replacing aged, cracked lamps, this Tresound light kit offers a practical, plug-and-play swap that preserves the vehicle's original look while improving weather resistance and durability. The kit is engineered for older body styles (classic/old body), not the 1999–2000 new-body models, and it fits Fleetside beds only. Each assembly is molded from robust ABS and undergoes factory quality checks to maintain consistent fit and finish.

Which vehicles and model years are compatible with these tail lights?

These tail lights cover a broad range of late‑model GM trucks and SUVs but are limited to classic body styles and Fleetside beds. Verify your truck's bed type and body year before ordering to avoid incompatibility.

• Chevy Silverado C/K 1500: 1988–1999
• Chevy Silverado C2500/C3500 & K2500/K3500: 1988–2000
• Chevy Suburban & Blazer, Tahoe: select years 1992–1999
• GMC Sierra, Yukon, Suburban: 1988–2000 depending on model; Cadillac Escalade 1999–2000

How simple is installation and what wiring is required?

Installation is designed to be straightforward for most DIYers: the assemblies are plug-and-play and use existing mounting points and socket harnesses. No major trimming or rewiring is typically necessary when replacing like-for-like lights on compatible trucks.

• Standard plug-in connectors match original harnesses on compatible models
• Uses factory bolt locations—no custom brackets required
• Basic tools (screwdriver, socket set) and about 30–60 minutes per side

What materials and durability features do these lights offer?

Tresound builds these lamps with heavy-duty ABS housings and a waterproof design to withstand road salts, moisture, and daily use. The production process includes strict in-factory quality inspections to help ensure long-term reliability and consistent fitment.

• ABS plastic housing for impact resistance
• Sealed construction for improved weather protection
• Factory-level quality control for consistent dimensions and finish

Are there any important fitment exclusions I should know about?

Yes. These lights do not fit Stepside bed trucks or the 1999–2000 new-body GM models. Always confirm whether your truck is Fleetside (smooth-sided bed) and check the body generation before purchasing.

• Not compatible with Stepside bed models
• Only fits old-body/classic GM trucks; not for 1999–2000 new-body designs
• Verify model and year against your vehicle's paperwork or VIN if unsure
