Rigid Industries 40-Inch Adapt E-Series Adaptive LED Light Bar | Auto Beam Control | Universal | 280413

Is This for You?

You're building a truck, SUV, UTV, or Jeep and you want a 40-inch adaptive light bar that automatically adjusts its beam pattern to match your speed and terrain — without manual input. The Rigid Industries 40-Inch Adapt E-Series (SKU: 280413) delivers Rigid's Adapt speed-indexed beam technology in the proven E-Series double-row platform. At low speed, the bar opens to a wide flood for trail navigation. As speed increases, it transitions through driving to a tight long-range spot for open-terrain and high-speed runs. The E-Series double-row configuration delivers more raw lumen output than the single-row Adapt platform at the same length — making this the higher-output choice for builds that need both adaptive beam control and maximum brightness.

The Result

40 inches of double-row adaptive illumination with automatic speed-indexed beam transitions. The E-Series platform's double-row LED configuration delivers higher lumen output than single-row Adapt bars at the same length — giving you more light on the ground at every beam setting. At $1,589.99, this is the performance-value choice in the Rigid Adapt lineup for builds that need wide coverage, long-range projection, and automatic beam management without the full-width footprint of the 50-inch platform.

Installation Notes

Professional installation recommended. Requires a compatible wiring harness, relay, and switch system — confirm harness compatibility with your vehicle before ordering. Verify mounting bracket clearance and structural load rating for the 15-lb bar weight before install. Confirm roof rack, bumper, or grille mounting geometry matches standard Rigid E-Series end-cap bolt pattern before ordering.

Engineering Question

Choosing between the Rigid 40-Inch Adapt E-Series (280413, double-row) and the Rigid 30-Inch Adapt E-Series (270413, double-row) for a roof rack build on a mid-size truck — at what point does the additional 10 inches of bar length on the 280413 produce a meaningful increase in peripheral coverage versus the 270413, and does the double-row configuration on both bars produce the same lumen-per-inch output? Contact OFAS with your roof rack dimensions, vehicle platform, and primary terrain profile and we'll confirm which Adapt E-Series length delivers the right coverage footprint for your specific build.
