Tresound LED Third Brake Cargo Light for 2014-2018 Silverado/Sierra

In this review the Tresound LED Third Brake Cargo Light is assessed as a practical replacement for later-model Chevrolet Silverado and GMC Sierra trucks that originally came with cargo lights. The bottom line: this unit is for owners who want a brighter, more modern high mount stop lamp with simple installation and improved visibility. It stands out because the LED array is noticeably brighter than the dull halogen-type factory lens and the design includes a waterproof ABS housing that helps prevent leaks while maintaining the original cargo and brake functions.

Key Features

• Waterproof Design: The ABS housing with high-density foam on the back reduces the risk of water and snow intrusion to protect internal electronics and maintain reliability.
• Vehicle Fitment: Designed specifically for 2014-2018 Chevrolet Silverado 1500 and 2015-2018 Silverado 2500HD/3500HD and compatible 2014-2018 GMC Sierra 1500 and 2015-2018 Sierra 2500HD/3500HD models, covering standard, extended and crew cab configurations.
• LED Brightness: The LED lighting is brighter than traditional halogen bulbs, improving rear visibility for braking and cargo illumination.
• Cargo & Brake Functions: The assembly supports both cargo light and brake lamp operations so it performs dual roles without changing truck wiring in most original cargo-light-equipped models.
• Plug-n-Play Installation: For trucks that came with cargo lights, the unit installs without rewiring, making the swap quick and straightforward for DIY install.
• Chrome Housing with Red Lens: The finish gives a clean, factory-like appearance that improves the look of an older truck while maintaining OEM styling.

Who It's For

This product is best for owners of 2014-2018 Chevrolet Silverado and 2014-2018 GMC Sierra trucks who want a straightforward, brighter replacement for the high mount stop lamp and cargo light. It especially suits those who value easy installation and a sealed housing to reduce water ingress.

Those who should look elsewhere include owners of 2014 old body style models and vehicles that were not originally equipped with cargo lights without willingness to perform minor modifications; non-cargo-light models may need adjustments to ensure proper function.
