Bolt-in LED “Power” bar custom-fit for 2020–2023 GMC Sierra 2500 & 3500 AT4. The 6,500–7,000K strip snaps into the factory grille with no cutting required, delivering a crisp DRL glow rated for 50,000 hours. The IP67-sealed housing shrugs off water, dust, and road salt, while your choice of stealth-black or classic-silver anodized frame keeps the look factory-clean.

Install is simple—bolt to stock points and connect with the included 4 foot lead. For a no-splice option, add the optional plug-and-play jumper for a quick, factory-style tie-in. The kit includes the grille light bar, stainless mounting hardware, 4 foot lead, and a six-month Sick Diesel Gear warranty.

  • One LED Grill Light top bar
  • Installation kit

AT4 2500 Grill light

Love my grill light on my AT4 2500. Unfortunately my light developed a dead spot within the first year. But the crew at Sick Diesel replaced it for me. All I had to do is send them a pic and they shipped a new one out right away. Thanks guys for standing behind your product!
