The Baja Designs GMC 2500/3500 Behind Grille Dual S8 Kit is a no-drill, no-cut lighting upgrade built for heavy-duty truck owners who demand serious trail and road illumination without compromising the factory look of their front end. Mounting behind the grille keeps the lights protected and the exterior clean, while the vehicle-specific brackets ensure a precise, rattle-free fit straight out of the box.
Each S8 light runs a Driving/Combo pattern, which layers a focused driving beam together with wide flood coverage so you get maximum trail visibility in a single bar — no mixing and matching beam patterns required. Whether you're hauling through back-country roads, working a job site after dark, or pushing deep into the bush, this setup fills in shadows on both sides of the trail while still throwing light far down the path ahead.
The included amber backlit wiring harness taps into your ignition so the accent LEDs activate automatically, adding a low-draw visibility feature that's practical on the trail and easy on the eyes on the road. Everything needed for a clean, integrated install comes in the kit, so your truck is ready to work the moment the wrench goes down.
