Tresound LED Third Brake Cargo Light for 2014–2018 Silverado & Sierra — Red Lens Chrome Housing, Plug-and-Play

The Tresound LED Third Brake Cargo Light is a direct-fit high-mount stop lamp that replaces the factory unit on compatible 2014–2018 Chevy Silverado and 2014–2018 GMC Sierra trucks, delivering brighter LED illumination with waterproof construction and plug-and-play installation.

This replacement rear high-mount stop lamp is engineered to match the mounting points and electrical connector of OEM cargo- or brake-only units for the listed Silverado and Sierra model years. Built from durable ABS with a chrome housing and red lens, it upgrades dim halogen output to a cleaner, more visible LED array while resisting moisture with a high-density foam seal. The unit supports cargo and brake lamp functions on compatible trucks and requires no rewiring in standard installations.

Will this light fit my Silverado or Sierra?

If your truck is a Chevrolet Silverado 1500 from 2014–2018 or a Silverado 2500HD/3500HD from 2015–2018, or a GMC Sierra 1500 from 2014–2018 or Sierra 2500HD/3500HD from 2015–2018, this lamp is designed to be compatible. It fits standard cab, extended cab, and crew cab configurations provided the vehicle originally used the cargo-style or high-mount brake light configuration.

• Compatible years: Silverado 1500 (2014–2018), Silverado 2500/3500 HD (2015–2018), Sierra 1500 (2014–2018), Sierra 2500/3500 HD (2015–2018)
• Fits Standard, Extended, and Crew Cab body styles
• Not compatible with 2014 old-body-style models
• May need minor modification if installed on a non-cargo-light original model

How simple is installation—do I need to rewire anything?

Installation is designed to be plug-and-play for trucks that came from the factory with the cargo-light wiring and connector. The lamp mounts into the existing bracket and connects to the stock harness, eliminating the need for cutting, splicing, or complex electrical work in most cases. For vehicles that originally had a different rear lamp configuration, small adjustments may be necessary to ensure proper function.

• Direct-fit connector for compatible factory harnesses
• No rewiring required for standard cargo-light equipped trucks
• Mounts using existing screws and brackets
• Minor modification could be required for non-cargo-original models

What performance and durability features does this lamp offer?

The Tresound LED third brake light uses bright LEDs that outshine traditional halogen bulbs, improving rear visibility and signaling response. Constructed from ABS with a chrome housing and a red lens, it includes a high-density foam backer to form a waterproof seal against rain and snow. The overall build is intended to withstand road vibration and harsh environmental exposure common to pickup truck usage.

• High-output LED array for clearer brake and cargo illumination
• ABS housing with chrome finish for corrosion resistance
• High-density foam backing to prevent water ingress
• Rated to resist snow, heavy rain, and road spray

Does this lamp support both cargo light and brake functions?

Yes—where the vehicle wiring supports both functions, the unit operates as a cargo light and as the high-mount brake lamp. It’s purpose-built for trucks that originally had cargo lights or combined brake/cargo lamp arrangements. If your truck was originally equipped without a cargo light, verify wiring compatibility before purchase to avoid function issues.

• Operates as cargo and brake light on compatible wiring setups
• Designed for models that originally had cargo light capability
• Check original vehicle equipment if unsure about compatibility
• Simple electrical check can prevent function mismatch

Who is this for: The Tresound LED third brake cargo light is aimed at Silverado and Sierra owners (specified years above) who want a brighter, more weather-resistant replacement for a worn or dim factory high-mount stop lamp. It’s ideal for drivers seeking an OEM-style fit with upgraded LED performance and minimal installation time, including fleet vehicles, daily drivers, and trucks frequently used in wet or snowy conditions.
