Fitment, Shipping & Product Support
The Baja Designs S8 Amber Backlight (704003) is a 40-inch LED light bar with white primary output and an independently controlled amber backlight strip. The primary LEDs output white light at full S8 output β maximum forward throw in clear conditions. The amber backlight is a secondary LED strip wired on its own circuit, used as a running light, marker, or accent independent of the main beam.
This is not the S8 Full Amber. The S8 Full Amber (704013) outputs amber from every primary LED β zero white output, built exclusively for dust, fog, sand, and rain where full amber spectrum is the priority across the entire bar. This bar runs white primary output with amber as a secondary function. If your primary environment is dust, fog, or sand and you need full amber output from every LED, 704013 is the correct bar.
The driving/combo pattern delivers long-range forward projection with lateral spread β the best all-around pattern for high-speed trail, desert, and road use where both forward reach and peripheral coverage matter simultaneously.
Universal mount. Brackets sold separately. Dual-circuit relay harness sold separately and required.

Critical Compatibility
| Configuration | Compatibility |
|---|---|
| Any mount not confirmed for 40-inch bar length and S8 mounting tab spacing | β Measure before ordering β 40-inch bar cannot be returned once mounting holes are drilled |
| Roof rack, bumper, or chase rack opening under 40 inches | β Not compatible β confirm mounting location accommodates full bar length before ordering |
| Single-circuit relay harness | β Not compatible β amber backlight and white primary LEDs are on independent circuits; dual-circuit harness required for independent control of both functions |
| Factory wiring without relay harness | β Not compatible β S8 draw exceeds factory switch circuit ratings |
| Full amber output as primary requirement in dust/fog/sand | β Use-case mismatch β primary LEDs output white; see S8 Full Amber 704013 for full amber output |
| On-road use in jurisdictions restricting auxiliary lighting | β Verify compliance with your state DMV or DOT before road use |

Installation Notes
Measure your mounting location before ordering. The S8 is 40 inches long. Confirm your roof rack, bumper, or chase rack opening accommodates the full bar length and S8 mounting tab spacing before purchasing. A 40-inch bar cannot be returned once mounting holes are drilled β measure first.
Mounting brackets are required and not included. Order vehicle-specific or universal S8 mounting brackets separately. Confirm bracket compatibility with S8 mounting tab dimensions before purchasing.
Dual-circuit relay harness is required. The amber backlight and white primary LEDs are wired on independent circuits β independent control of both functions requires a dual-circuit relay harness. A single-circuit harness will not provide independent backlight control. Confirm your harness supports dual-circuit operation before ordering. Not included.
Aim before final torque. Set beam angle at your intended aim point before fully torquing mount hardware. Driving/combo pattern should be aimed to balance forward reach and peripheral spread for your mounting height and application.
Connector sealing. Fully seat and weatherproof all wiring connectors after installation. IP69K rating applies to the bar housing β connector integrity is installer responsibility.
Road legality. Auxiliary lighting regulations vary by state. Verify compliance with your state DMV or DOT before on-road use.

The Obsidian Take
The S8 Amber Backlight is the correct bar for the driver who needs maximum white primary output for high-speed trail, desert, and road use and wants an independently controlled amber strip for running light or marker function without sacrificing primary output. White primary LEDs give you full S8 output in clear conditions β the amber backlight adds a secondary function on its own circuit without touching the main beam.
If your environment is consistently dust, fog, sand, or rain and you need amber output from every LED across the entire bar, this is the wrong configuration. Run 704013 β full amber output, every primary LED, no white output, built for exactly those conditions.
If you want a pure white bar with no backlight, there are S8 variants without the amber strip. If you want spot or flood patterns instead of driving/combo, confirm the correct S8 pattern SKU for your application before ordering.
The S8 Amber Backlight is the all-conditions bar β maximum white output when the air is clean, amber presence light when you need it, and IP69K construction that handles whatever the environment delivers.
Common Questions
What is the difference between the S8 Amber Backlight and the S8 Full Amber?
The S8 Amber Backlight (704003) runs white primary LEDs at full output with an independent amber strip for running light or accent use. The S8 Full Amber (704013) outputs amber from every primary LED β zero white output, built for dedicated dust, fog, sand, and rain use. If you need full amber spectrum output across the entire bar, 704013 is the correct bar.
Do I need a special wiring harness for the amber backlight?
Yes. The amber backlight and white primary LEDs are on independent circuits. A dual-circuit relay harness is required to control both functions independently. A single-circuit harness will not provide independent backlight control. Confirm your harness supports dual-circuit operation before purchasing.
Are mounting brackets included?
No. Universal or vehicle-specific S8 mounting brackets are sold separately. Confirm bracket compatibility with S8 mounting tab spacing before purchasing.
Will this fit my roof rack / bumper / chase rack?
Confirm your mounting location accommodates 40 inches of bar length and S8 mounting tab spacing before ordering. Measure first β a 40-inch bar cannot be returned once mounting holes are drilled.
Is auxiliary lighting legal on public roads?
Auxiliary lighting regulations vary by state. Verify compliance with your state DMV or DOT before on-road use.
Verified Fitment
