Baja Designs S8 Straight LED Light Bar — Universal SKU: 705013 | Universal | 50-Inch | Driving/Combo | Baja Amber | Amber Backlit

A slim, 50-inch Cree LED light bar built on Baja Designs' S8 platform — aircraft-grade aluminum housing with Mil-Spec hard anodize, 31,750 lumens in a Driving/Combo beam pattern, and an amber backlit feature that gives the bar a distinctive secondary ambient glow. Eight LEDs per 10-inch section. 1.6-inch profile height. Wiring harness sold separately.

Before ordering: This is a universal light bar. No wiring harness is included. For this 50-inch bar, the correct harness is PN 640122 (On/Off with mode switch for backlight). PN 640115 is for 10–30 inch S8 bars only and is not compatible with this 50-inch configuration. Mounting brackets are included. Confirm your mounting surface before ordering.

Required separately: Wiring harness PN 640122 (On/Off with mode switch for backlight) — required to operate this light bar and control the amber backlight feature. Sold separately. Do not use PN 640115 with this 50-inch bar.

Component Specifications

What Is and Is NOT Included

Included:

• S8 Straight LED Light Bar, 50-inch, Driving/Combo, Baja Amber
• Mounting brackets (stainless steel)

Not included:

• Wiring harness PN 640122 (On/Off with mode switch for backlight) — required for this 50-inch bar, sold separately
• PN 640115 is not compatible with this bar — that harness covers 10–30 inch S8 configurations only

Critical Compatibility

• Wiring harness not included: PN 640122 (On/Off with mode switch for backlight) is the required harness for this 50-inch bar. It controls both the main beam and the amber backlight feature. Do not use PN 640115 — that harness is rated for 10–30 inch S8 bars only.
• Amber backlit feature: This bar includes an amber backlight in addition to the primary forward beam. The amber backlight mode is controlled by the PN 640122 harness mode switch. Confirm your wiring plan accounts for this feature before ordering.
• Baja Amber lens: Primary output light appears amber-colored. Select Baja Amber for improved performance in dust, fog, rain, and similar conditions. For maximum raw lumen output in clear conditions, see the clear-lens S8 variant.
• Slim profile: At 1.6 inches tall and 3 inches deep, the S8 is significantly slimmer than the OnX6+ platform (2.69 inches tall). Confirm your mounting clearance before ordering.
• Universal fitment: Mounting brackets are included. No vehicle-specific hardware is included beyond what is in the box.
• 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 S8 Straight mounts using the included stainless steel mounting brackets. Wiring harness PN 640122 must be sourced separately before installation — the bar cannot be operated without it.

Refer to the current Baja Designs installation instructions for SKU 705013 for complete procedures, torque specifications, and wiring diagrams.

The Obsidian Take

The 705013 is the 50-inch S8 in Baja Amber with amber backlight — the thinnest LED light bar in the Baja Designs catalog at 1.6 inches tall, built on aircraft-grade aluminum with billet machined bezel and 40 Cree LEDs running 8 per 10-inch section. The amber backlight is a distinctive S8 feature that the OnX6+ platform doesn't offer — it provides an ambient secondary glow that distinguishes the bar's appearance in addition to the primary beam. The correct harness for this 50-inch bar is PN 640122, not PN 640115 — that distinction matters and is easy to miss on the Baja Designs site. Order the harness before this bar ships or installation stops on day one.

This Product Is For You If

• You want a slim-profile (1.6-inch height) LED light bar in a 50-inch straight configuration.
• You want Baja Amber output for improved performance in dust, fog, and precipitation.
• You want the amber backlight feature as a secondary aesthetic and visibility element.
• You are prepared to source wiring harness PN 640122 separately before installation.
• You want Cree LED technology with Mil-Spec housing and IP69K waterproofing.

This Product Is Not For You If

• You do not have or are not prepared to source wiring harness PN 640122 before installation.
• You want a clear lens — clear-lens S8 variants are available separately.
• You want High/Low beam switching — the S8 platform does not have Hi-Lo beam functionality.
• You want the OnX6+ platform with higher raw lumen output — see the OnX6+ Straight or Arc series.
• You need a bar shorter than 50 inches — other S8 lengths are available down to 10 inches.

Product Family Reference

The S8 platform is available from 10 to 50 inches. Harness selection depends on bar length — confirm the correct harness for your size before ordering.

For the OnX6+ platform with Hi-Lo beam switching in a 40-inch format, see SKU 454013 (Baja Amber) or SKU 524003 (Clear Arc).

Common Questions

Is a wiring harness included?
No. Wiring harness PN 640122 (On/Off with mode switch for backlight) is required for this 50-inch bar and is sold separately. Do not use PN 640115 — that harness is for 10–30 inch S8 bars only.

What is the amber backlight feature?
The S8 includes an amber backlight that provides a secondary ambient glow independent of the primary forward beam. The PN 640122 harness mode switch controls the backlight. This feature is unique to the S8 platform and is not available on the OnX6+ series.

Does this bar have High/Low beam switching?
No. The S8 50-inch bar is a single-output forward beam with an amber backlight feature. It does not have High/Low beam switching.

Why choose Baja Amber over Clear?
Baja Amber improves contrast and penetration in suspended particles — dust, fog, rain, and snow. Clear lens provides maximum raw lumen output in open, unobstructed conditions.

What makes the S8 different from the OnX6+?
The S8 has a significantly slimmer profile (1.6-inch height vs. 2.69 inches for the OnX6+) and includes an amber backlight feature. The OnX6+ offers higher peak lumen output and Hi-Lo beam switching. Both use aircraft-grade aluminum housing and IP69K waterproofing.

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.
