Rough Country 10" Slimline Black Series LED Light Bar

Your OBS Chevy or GMC didn't come with enough light for what you actually do with it. Stock headlights were designed for suburban streets in 1988, not the fire roads, deer leases, and dark trailheads you're running today. The Rough Country 10-Inch Slimline Black Series LED Light Bar fixes that without turning your front end into a spotlight rig.

This bar is built low-profile on purpose. Ten 5-watt CREE LEDs are packed into a slim, panel-style housing that mounts flush and clean — up on a roof rack, across a grille guard, tucked under a bumper, or zip-tied to a light bar mount for scouting the trail ahead. On a 1988-1999 C/K1500, C/K2500, or C/K3500, that low mounting profile means it tucks in without blocking your factory grille airflow or looking like an afterthought.

Where this bar earns its keep is the 90-degree flood pattern. You get 4,000 lumens spread wide and even across the scene in front of the truck, not a narrow laser beam fifty yards down a two-track. That's exactly the kind of light you want when you're backing a trailer into a dark camp spot, working the winch after dark, checking a trail obstacle before you commit the truck to it, or just want to see the whole ditch line instead of a keyhole of brightness.

Built for real off-road use, not just the catalog photo. The housing is die-cast aluminum for strength and heat dissipation, sealed to an IP67 waterproof rating so mud, creek crossings, and driving rain don't take it out of commission. Rough Country also builds in Moisture Breather technology, which keeps the lens from fogging up on cold mornings or after a good soaking.

Installation is straightforward: it ships with a premium flat-wound wiring harness and an on/off switch, so you're not fabricating your own relay setup just to get it running. Most OBS truck owners have this mounted and wired in under an hour with basic hand tools.

At 10 inches, this is the size that works when you don't have room — or don't want the look — of a full-width bar. For OBS trucks running a grille guard or bumper-mounted bracket, this is the size that doesn't overwhelm the front end. Whether you're running trails after work, setting up camp in the dark, or just tired of squinting into unlit backroads, the 10-inch Slimline gives your OBS truck real, usable light without the bulk.
