OKLPF Rear Brake Tail Lights for GMC Sierra 2007-2014 — Direct-Fit Replacement, Plug-and-Play

These OKLPF rear brake tail lights are direct-fit replacements designed to restore brake, turn and running light functions on compatible GMC Sierra 1500, 2500HD, and 3500HD models from 2007–2014.

If your Sierra’s rear lights are cracked, faded, or no longer functioning, swapping in a pair of OKLPF tail lights gives you a factory-style look with straightforward installation. Each lamp is engineered to match the original mounting points and electrical connectors for an efficient plug-and-play swap. The housings are tested for environmental durability, and the assemblies replace specific GM part numbers to maintain proper fit and function.

How close is the fit and what OEM parts do these replace?

OKLPF designs these assemblies to align with the factory mounting points and electrical connectors so installation is simple. They are intended as direct replacements for the indicated GM part numbers, which helps ensure proper alignment and function with your truck’s wiring and body openings.

• Replaces left (driver) part numbers GM2800208 and 25958484.
• Replaces right (passenger) part numbers GM2801208 and 25958485.
• Plug-and-play harness compatibility minimizes the need for splicing or adapter parts.

What durability tests and quality checks do these tail lights undergo?

To help them hold up to daily use and harsh conditions, OKLPF subjects these tail light assemblies to several environmental tests. The goal is to reduce premature failure from moisture, dust, salt, or temperature extremes while maintaining consistent light output.

• Salt spray testing to assess corrosion resistance for coastal or winter-road exposure.
• Humidity and temperature cycling to evaluate seals and housing stability.
• Dust and water ingress testing to help prevent leakage and internal contamination.

How difficult is installation and what tools are required?

Installation is designed to be straightforward for anyone comfortable with basic vehicle light replacement. The assemblies are made for direct plug-and-play connection and attach at the original factory mounting points, saving time compared with custom or modified setups.

• Typical tools: socket set, screwdriver, and light trim removal tool (optional).
• No wiring modifications required for compatible Sierra models—simply unplug the old unit and plug in the new one.
• Expect a 20–45 minute install per side for most owners.

Who this is for: Drivers who own a compatible GMC Sierra 1500, 2500HD, or 3500HD and need a dependable, OEM-style tail light replacement without aftermarket rewiring. These OKLPF lights suit owners repairing damage, replacing faded lenses, or restoring factory appearance on non-Denali and non-dually Sierra variants that use the specified bulb and connector types.
