Baja Designs OnX6+ Straight LED Light Bar — Universal SKU: 454013 | Universal | 40-Inch | Straight | Driving/Combo | Baja Amber

The OnX6+ Straight is Baja Designs' race-proven, mil-spec LED light bar platform in a 40-inch straight configuration with a Baja Amber lens. High-speed spot reflectors and next-generation LEDs deliver 38,900 lumens on high through a Driving/Combo beam pattern illuminating zones 1 through 4 simultaneously while pushing into zone 5. Aircraft-grade aluminum housing with Mil-Spec hard anodize, IP69K waterproofing, and High/Low beam switching are standard on the 40-inch bar. Wiring harness sold separately.

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 (OnX6+ 30–50 inch applications). Do not use PN 640115 for this bar — that harness is for 10–20 inch OnX6+ bars only. Mounting brackets are included. Confirm your mounting surface before ordering.

Required separately: Wiring harness PN 640119 (OnX6+ 30–50 inch) — required to operate this light bar, sold separately.

Component Specifications

What Is and Is NOT Included

Included:

• OnX6+ Straight LED Light Bar, 40-inch, Driving/Combo, Baja Amber
• Mounting brackets (stainless steel)
• Hi-Low dongle

Not included:

• Wiring harness — PN 640119 (OnX6+ 30–50 inch) required, sold separately. Do not use PN 640115 — that harness is for 10–20 inch bars only.

Critical Compatibility

• Wiring harness not included: This light bar does not ship with a wiring harness. PN 640119 is required for all 30–50 inch OnX6+ bars. PN 640115 is for 10–20 inch bars only and is not compatible with this SKU.
• High/Low beam: This 40-inch bar has High/Low beam switching. The 50-inch OnX6+ does not have Hi-Lo — it is pre-dimmed. Confirm your size selection before ordering.
• Baja Amber lens: This SKU uses a Baja Amber hardcoated polycarbonate lens. Output light appears amber-colored. This is distinct from clear-lens OnX6+ variants. Select Baja Amber for improved contrast in fog, dust, and precipitation conditions.
• Straight profile: This is the straight-bar configuration. For a curved bar that follows a bumper contour, see the OnX6+ Arc variants.
• Universal fitment: Mounting brackets are included. No vehicle-specific bracket hardware is included beyond what is 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 recommended. The OnX6+ Straight mounts using the included stainless steel mounting brackets. Vertical adjustment can be made and locked in to optimize the beam pattern for the specific mounting position. 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 454013 for complete procedures, torque specifications, and wiring diagrams.

The Obsidian Take

The 454013 is the 40-inch straight OnX6+ in Baja Amber — the same aircraft-grade aluminum, Mil-Spec hard anodize, billet bezel, and 38,900-lumen output platform as the clear-lens straight variants, filtered through an amber lens for improved contrast in dust, fog, and precipitation. The choice between amber and clear comes down to intended use: clear maximizes raw visibility in open conditions; amber reduces glare scatter in suspended particles. For the 40-inch bar, that's the only difference — Hi-Lo switching, IP69K waterproofing, MIL-SPEC durability, and PN 640119 harness requirement are identical across lens colors. Don't order without the harness — this bar does not function without it and it ships without one.

This Product Is For You If

• You want a high-output 40-inch straight LED light bar with 38,900 peak lumens and High/Low beam switching.
• You want Baja Amber lens output for improved performance in dust, fog, or precipitation.
• 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 IP69K weatherproofing and MIL-SPEC durability in a universal straight-bar format.

This Product Is Not For You If

• You do not have or are not prepared to source wiring harness PN 640119 before installation.
• You want a clear lens — clear-lens OnX6+ variants are available separately.
• You want an arc profile bar that follows a bumper contour — see the OnX6+ Arc variants.
• 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.

Common Questions

Is a wiring harness included?
No. Wiring harness PN 640119 (OnX6+ 30–50 inch) is required and sold separately. Do not use PN 640115 — that harness is for 10–20 inch bars only and is not compatible with this SKU.

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

Why choose Baja Amber over Clear?
Baja Amber lens output improves contrast and penetration in suspended particles — dust, fog, rain, and snow. Clear lens provides maximum raw lumen output in open, unobstructed conditions. Amber is commonly preferred for desert and off-road trail applications where dust is a primary concern.

What is the difference between this bar and the OnX6+ Arc?
This SKU (454013) is a straight bar. The OnX6+ Arc has a curved profile designed to follow the contour of bumpers and windshields for a factory-fit appearance and wider illumination angle. Lumen outputs are similar across both platforms.

Can I use the PN 640115 harness with this bar?
No. PN 640115 is for OnX6+ bars in the 10–20 inch range only. The correct harness for this 40-inch bar is PN 640119.

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 warranty?
Baja Designs provides a Limited Lifetime Warranty and a 30-Day Money Back Satisfaction Guarantee.
