OKLPF Rear Brake Tail Light Pair for 2007–2014 GMC Sierra — Red, Includes Bulbs & Harness

This pair of red rear brake tail lights from OKLPF restores rear visibility and turn/brake signals for a range of GMC Sierra models. Built to match the fit and function of the original assemblies, the set includes driver and passenger side lights, bulbs, and the required harness for a direct plug-and-play swap. The housings are tested for temperature, humidity, dust, salt spray, and water to help endure daily road conditions and seasonal exposure.

Will these tail lights fit my GMC Sierra?

They are compatible with many 2007–2014 Sierra models, but not every variant. Verify your year and model before ordering to ensure correct fitment.

• Fits: 2007–2013 Sierra 1500 (selected years), 2007–2014 Sierra 2500HD and 3500HD (selected years).
• Replaces OE part numbers: left/driver 25958484 (GM2800208) and right/passenger 25958485 (GM2801208).
• Not compatible with Denali trims, 2007 Classic models, 3500 dually configurations, or 2010–2011 tail lights with 921 backup bulbs.

How simple is the installation process?

Installation is intended to be straightforward and requires no special tools for most owners. The assemblies come with bulbs and harness so you can swap them directly into the factory mounting points.

• Direct plug-and-play wiring harness included to match factory connectors.
• Pre-installed bulbs mean no separate bulb purchases or additional wiring modifications.
• Standard bolt locations mirror OE parts for fast, secure mounting.

What durability and testing does OKLPF perform?

These tail lights undergo environmental and durability tests aimed at reliable performance in everyday driving conditions. While no light is indestructible, the assemblies are built to resist common stressors encountered on the road.

• Salt spray and corrosion testing for coastal and winter use.
• Temperature and humidity cycles to check seal integrity and material stability.
• Dust and water resistance tests to reduce risk of interior fogging or electrical issues.

What should I check before ordering and after installation?

Confirm vehicle compatibility and inspect wiring and lamp functions right after installation to ensure everything operates as intended. Small differences between model years can affect fitment or bulb type.

• Verify your truck’s year, model, and bed configuration against the compatibility list.
• After install, test brake, turn signal, reverse, and running lamp functions immediately.
• Check mounting points and gaskets for good sealing to prevent moisture ingress.

Who is this for: This OKLPF tail light pair is tailored for GMC Sierra owners (2007–2014 ranges listed) who need direct replacement rear signal assemblies that match factory fitment. It’s a practical choice for DIY installers, fleet maintenance teams, and drivers replacing worn, cracked, or nonfunctional tail lights—provided the vehicle is not a Denali, 2007 Classic, 3500 dually, or a Sierra with 2010–2011 921 backup bulb configurations.
