40 Inch LED Light Bar Amber S8 Series Baja Designs

The Baja Designs S8 Series 40-inch LED light bar is built around a slim, section-based architecture — eight LEDs per 10-inch section — delivering serious output in a low-profile housing. This bar features Baja Designs' CopperDrive technology, meaning every LED runs at 100% drive current, not throttled down to extend lifespan at the cost of output. The result is a 5000K daylight color temperature that reduces driver fatigue and renders terrain in natural light. The amber backlight is a standout feature here — it's integrated, not an afterthought, and adds a secondary lighting mode that sets this bar apart from single-function units.

MoistureBlock construction makes it fully submersible, not just splash-resistant. Lenses and optics are field-replaceable through Baja Designs' uService program, which matters when you're running a light this size in real conditions. The bar ships without a wiring harness — you'll need either the 640122 (on/off with backlight mode switch) or 640115 (on/off 3-pin, suited for 10–30 inch units) depending on your setup.

We like that Baja Designs backs this with a 30-day money-back guarantee and a Limited Lifetime Warranty. At 40 inches, this bar is a significant investment — that coverage matters. Confirm harness compatibility before ordering.
