40 Inch LED Light Bar OnX6 Arc Series Baja Designs

The Baja Designs OnX6+ Arc Series 40-inch LED light bar brings a driving/combo beam pattern, a gently arched profile designed to follow the contour of a bumper or windshield, and a clear lens — all in a bar that measures 4.29 inches deep. High-speed spot reflectors push output farther down the road, and the next-generation LEDs are rated to 50,000 hours of life at a 5000K color temperature. That daylight-matched output reduces eye fatigue on long night runs and makes trail features easier to read.

The 5000K rating isn't just a spec number — it's the reason Baja Designs leans on the ClearView and CopperDrive technologies here. CopperDrive keeps LEDs running at 100 percent of their rated current, while MoistureBlock seals the unit against rain and submersion. Lenses and optics are field-replaceable through Baja Designs' uService program, so the bar isn't a throw-away if something gets damaged.

This bar ships without a wiring harness. To power it, add Baja Designs PN 640119 (Hi-Power w/Mode Switch, 2-light max) or the Hi Beam Harness/Splitter PN 640163. Both are available as add-ons. The unit carries a limited lifetime warranty and a 30-day money-back guarantee, which we consider a meaningful commitment for a light bar at this build level.

Available options:

• Beam Pattern: Driving/Combo, High Speed Spot, Wide Driving
