The Baja Designs OnX6 Arc Dual Control 30in LED light bar (MPN 523003DC) is a curved, 30-inch bar built on the brand's OnX6+ Arc platform. The manufacturer lists a black aircraft-grade aluminum housing with a Mil-Spec hard anodize finish, a hardcoated polycarbonate lens, and a billet machined aluminum bezel. The main reason to choose it over a single-circuit bar is the dual control: a second power cord and switch lets you run the inner and outer LED sections separately, so one housing gives you amber or white light without mounting two bars.
The manufacturer classifies this bar as universal, so fit depends on your mounting location and bracket clearance rather than a model-specific kit. Power is the main planning item. The bar ships without a wiring harness, and the manufacturer specifies harness sets for basic on/off and for high/low operation. Owners on user forums say factory upfitter circuits are often too light for a bar of this size, so a separate relay for each section is a common approach. For buyers searching for an OnX6 Arc dual control amber white light bar, a 30 inch curved driving/combo LED bar, or Baja Designs 523003DC relay wiring, the value is in the split control and the bundled hardware, and the manufacturer's installation sheet for this SKU should be reviewed before drilling.
No. The manufacturer states the bar ships without a harness. For basic on/off operation it specifies two 64-0115 harnesses, and for high/low access it specifies one 64-0119 plus one 64-0115.
Yes. The manufacturer describes the second power cord and switch as the means to control the inner and outer sections individually, which lets you run amber, white, or both.
Owners on user forums report that factory upfitter switches can be rated below what a bar like this draws, and they commonly add relays. Confirm your switch rating and the bar's current draw with the manufacturer before wiring directly to a factory circuit.
Mounting uses the included stainless steel brackets, so the physical install is manageable for a mechanically inclined owner. Wiring is the more involved step. Owners on user forums report that the factory-wired upfitter lead is often too thin for a dual-circuit bar, and that a harness without a built-in relay still needs external relays, typically one per section. Some harnesses also carry extra power and ground leads that do not plug directly into an upfitter switch, so plan the splice before you start. Use inline fusing at the battery, route the wiring through the windshield seal or a wire-hider path, and follow the manufacturer's installation sheet for the SKU.
