2020-2023 GM HD Smoked LED Sidemarkers Set (DIODD5127)

If you are looking to give your GMC Sierra HD a major styling upgrade without the complexity of extra wiring, the Smoked Standard LED Sidemarkers are the perfect solution. These markers are a complete, plug-and-play replacement for your factory fender lights, offering a much more modern and aggressive look than the stock units. The Smoked lens option provides a dark, blacked-out appearance that blends seamlessly with the factory trim when the lights are off, eliminating the distracting "orange and red" look of OEM markers. Once powered up, they reveal a crisp, high-intensity amber glow that is significantly brighter than the factory bulbs.

Features

• Modern Smoked Aesthetic: The dark-tinted lenses provide a blacked-out, stealthy appearance that complements any trim level or paint color.
• High-Intensity LED Output: Features high-power LED emitters that are significantly brighter than factory incandescent bulbs for improved visibility and safety.
• Fully Illuminated Housing: Utilizes an inner diffusing lens combined with an outer lens to create a perfectly even, uniform amber glow without visible "hot spots" or pixelation.
• OEM-Grade Construction: Designed using original CAD data for a perfect factory fit and built with UV-stable materials to prevent fading or yellowing over time.
• True Plug-and-Play: Fits directly into the factory mounting locations and plugs into the existing bulb sockets—no wiring, splicing, or tools required for installation.
