Baja Designs OnX6+ Arc LED Light Bar — Universal SKU: 524003 | Universal | 40-Inch | Driving/Combo | Clear | High/Low Beam

The OnX6+ Arc LED Light Bar is Baja Designs' curved LED light bar engineered to match the contour of bumpers and windshields for a factory-fit profile and wider field of illumination. The 40-inch bar delivers 39,220 lumens on high and 32,760 lumens on low through a Driving/Combo beam pattern, built on aircraft-grade aluminum with Mil-Spec hard anodize and next-generation LEDs rated at 49,930 hours. High/Low beam functionality is standard on the 40-inch bar.

Before ordering: This is a universal light bar — no vehicle-specific mounting brackets or wiring harness are included. A wiring harness is required and sold separately: PN 640119 (Hi-Power w/Mode Switch, 2-light max). Mounting brackets are included. Confirm your mounting surface and harness needs before ordering. This is an off-road lighting product — buyer is responsible for compliance with all applicable laws regarding auxiliary lighting use on public roads.

Required separately: Wiring harness PN 640119 (Hi-Power w/Mode Switch, 2-light max) — required to operate this light bar, sold separately.

Not included:

• Wiring harness — PN 640119 (Hi-Power w/Mode Switch, 2-light max) required, sold separately

Critical Compatibility

• Wiring harness not included: This light bar does not ship with a wiring harness. PN 640119 (Hi-Power w/Mode Switch, 2-light max) is required and sold separately. Do not order this light bar without also sourcing the harness.
• High/Low beam: This 40-inch bar has High/Low beam functionality. The 50-inch OnX6+ Arc does not have Hi-Lo — it is pre-dimmed. Confirm your size selection before ordering.
• Arc profile: The bar is curved to match the contour of bumpers or windshields. Confirm your mounting surface accepts an arc-profile bar before ordering.
• Universal fitment: No vehicle-specific mounting brackets are included beyond the stainless steel mounting brackets in the box. Confirm your mounting application before ordering.
• Off-road use: Some lighting outputs may not be legal for use on public roads. Buyer is responsible for compliance with all applicable laws and regulations.

Installation Notes

Professional installation is strongly recommended. The OnX6+ Arc mounts using the included stainless steel mounting brackets. The arc profile is designed to follow the contour of a bumper or windshield. The Hi-Low dongle is included — wiring harness PN 640119 must be sourced separately before installation.

Refer to the current Baja Designs installation instructions for SKU 524003 for complete procedures, torque specifications, and wiring diagrams.

The Obsidian Take

The OnX6+ Arc is Baja Designs' premium LED light bar — aircraft-grade housing, billet machined aluminum bezel, 39,220 lumens on high, and a curved profile that follows the bumper or windshield line for a cleaner, wider illumination footprint than a straight bar. The 40-inch configuration has full High/Low beam functionality (the 50-inch does not — it's pre-dimmed, a key distinction when sizing). At 340W on high, this bar draws significantly more power than the XL Linkable platform — confirm your vehicle's electrical system and wiring harness capacity before ordering. The harness (PN 640119) is non-negotiable: the bar does not function without it and it does not ship with one.

This Product Is For You If

• You want a high-output curved LED light bar with 39,220 peak lumens and High/Low beam switching.
• You want a bar profile that follows a bumper or windshield contour rather than a straight-line installation.
• You are prepared to source wiring harness PN 640119 separately before installation.
• You want aircraft-grade aluminum construction with Mil-Spec hard anodize and a billet machined aluminum bezel.
• You want 5000K daylight color output with IP69K weatherproofing and MIL-SPEC durability.

This Product Is Not For You If

• You do not have or are not prepared to source wiring harness PN 640119 before installation.
• You need a 30-inch or 50-inch bar — those are separate SKUs. The 50-inch does not have Hi-Lo beam switching.
• You want a vehicle-specific plug-and-play kit — this is a universal bar requiring separate bracket and harness sourcing.
• Your mounting surface does not accommodate an arc-profile bar.

Product Family Reference

The OnX6+ Arc is available in 30, 40, and 50-inch lengths. High/Low beam is available on the 30 and 40-inch bars only. The 50-inch bar is pre-dimmed without Hi-Lo functionality.

All sizes require wiring harness PN 640119, sold separately. All use the same arc profile.

Common Questions

Is a wiring harness included?
No. Wiring harness PN 640119 (Hi-Power w/Mode Switch, 2-light max) is required and sold separately. The bar cannot be operated without it.

Does this bar have High/Low beam switching?
Yes. The 40-inch OnX6+ Arc has full High/Low beam functionality. Note: the 50-inch version does not have Hi-Lo — it is pre-dimmed.

What is the arc profile and how does it affect installation?
The arc profile means the bar is curved rather than straight, designed to match the contour of a bumper or windshield. Confirm your mounting surface accommodates this profile before ordering.

What makes the OnX6+ different from standard straight light bars?
The curved arc profile provides a wider field of illumination and a factory-fit appearance on contoured bumpers and windshields. The aircraft-grade aluminum housing with Mil-Spec hard anodize and billet machined aluminum bezel represent a step up in construction quality.

How waterproof is this light bar?
IP69K rated — waterproof to 9 feet and pressure washable. The system also exceeds MIL-STD-810G and is IK10 impact resistant.

What is the color temperature?
5000K Daylight — engineered to mimic natural sunlight, improve trail recognition, and reduce eye fatigue on long runs.

What is the warranty?
