Baja Designs' S2 Sport line supplies the core hardware in this reverse kit: two wide cornering, clear-lens LED pods. Each light is listed at 1,581 lumens and 12.42 watts, with a 0.9 amp draw. Baja says the pods light up Zone 8 behind the truck, the area that matters most for reversing and towing. The kit is built for the 2020–2023 GMC Sierra 2500HD and 3500HD, and the pods include built-in overvoltage protection. Compared with a generic pod set, this kit's advantage is the fit and sealing. The lights are rated MoistureBlock waterproof, rain proof, and submersible, and the brand backs them with a limited lifetime warranty and a 30-day money-back guarantee. Owners on user forums who installed a Baja S2 backup harness said it needed no splicing or modification of the factory harness, with all waterproof connectors. That matters because a cheaper set usually leaves you to tap and seal the wiring yourself. Fitment details vary across sources, so confirm your truck's model year and cab configuration with the manufacturer before ordering. The kit includes two S2 Sport lights, a wiring harness, a splitter harness, and all necessary hardware for installation. Searches for a 2020-2023 GMC Sierra 2500HD reverse light kit, a Baja S2 Sport wide cornering clear light, or a plug-and-play HD truck backup harness should lead to this SKU.
The manufacturer lists this kit for the 2020–2023 GMC Sierra 2500HD and 3500HD. The manufacturer's listing for the same SKU also references Sierra 1500 model years, so confirm the application with the manufacturer before ordering for a 1500.
The manufacturer describes the kit as having a plug-and-play wiring harness and precision-fit brackets. Owners on user forums who installed a Baja S2 backup harness reported no splicing into the factory harness, but confirm routing against the manufacturer's installation sheet.
The manufacturer offers a limited lifetime warranty and a 30-day money-back guarantee on this kit.
The manufacturer describes this kit as easy to install, with precision-fit brackets and a plug-and-play harness, so it is generally a bolt-on job rather than a custom wiring project. Baja Designs publishes an installation sheet for SKU 447853, and that document should be your guide for bracket placement, harness routing, and the tool list. Before you start, confirm your truck's model year against the fitment above, and check the install sheet for any drilling or trimming steps before you cut or mark anything. Keep the splitter harness and wiring connectors dry during routing, since the lights are rated for submersion but the harness connections are only as good as your sealing.
