ROCCS LED Side Marker Lights for GMC Sierra 2500/3500 (2020-2026) — 4PCS White Clear Lens, OEM-fit Plug-and-Play

Upgrade the factory orange markers with a modern clear-lens LED solution engineered to match the OEM fitment for Sierra 2500/3500 models from 2020 through 2026. These four-piece sets include two front and two rear markers that use durable ABS housings and polycarbonate lenses to resist corrosion, scratches, and moisture while providing multiple light functions such as running, turn signal, hazard, and courtesy modes.

How easy is installation and will these trigger dash errors?

Installation is designed to be straightforward: each lamp plugs into the factory connector without rewiring or splicing. The kit was built to be compatible with the original electrical system so you shouldn't experience error codes, hyper-flash, or interference when installed correctly.

• Plug-and-play connectors match GM factory sockets
• No additional resistors or modules required in most installations
• Works with running lights, turn signal, hazard, and courtesy functions
• Fits OEM locations meant for part numbers 84806032, 84185031, GM2550207

What performance and durability features does this LED kit offer?

These markers use full LED illumination for higher brightness and longer service life compared with incandescent bulbs. The housing materials and sealed lens protect internal components from water, salt, and debris to keep the lights functioning in off-road or winter conditions.

• High-output LEDs for improved on-road visibility
• ABS housing and polycarbonate lens for impact resistance
• Waterproof construction to resist rain and road spray
• Estimated long lifespan—rig built for thousands of hours of use

Will these change my truck’s appearance or lighting behavior?

The clear lens and white LED aesthetic replace the factory amber look with a cleaner, more contemporary finish while maintaining all original light functions. Because they support turn and hazard signals, they preserve required signaling behavior while giving the truck a refreshed visual profile.

• Clear lens for a modern, streamlined appearance
• Maintains amber signaling behavior where required by vehicle wiring
• Provides a brighter, crisper light signature at night and in daylight
• Contoured design follows the Sierra fender and bumper lines
