Rough Country 12" Spectrum Series Single Row LED Light Bar

The Rough Country 12-Inch Spectrum Series LED Light Bar brings a different look and a different beam to your 1988-1999 Chevy or GMC OBS truck: a bezel-less, ultra-sleek housing packing 60 watts and 5,400 lumens from 12 five-watt Osram LEDs, with combined spot and flood beam patterns in a single bar.

That dual beam pattern matters on the trail — you get distance projection to spot obstacles or trail markers ahead, and wide-angle flood coverage to light up the immediate area around the truck, instead of choosing one or the other. Whether you're overlanding backroads, rock crawling, or just running trails after work, the Spectrum's combined beam gives you more usable light for the way OBS trucks actually get driven.

Built for real durability: IP67/IP69K waterproof rating (which covers high-pressure, high-temperature washdowns, not just rain), an impact and UV-resistant lens, and a tinted diffused lens that cuts glare while keeping output high. The diecast aluminum housing keeps things solid mounted to a bumper, grille guard, or roof rack.

For OBS owners who want a light bar with a more premium look than the standard Black Series line — bezel-less styling that reads as an upgrade rather than a basic add-on — the Spectrum 12-inch single row bar delivers both the appearance and the dual-beam performance to back it up. It's the light bar to reach for when you want your OBS build's lighting to look as thought-out as the rest of the truck.
