Perfect Fit for 4th & 5th Gen 4Runner Roof Racks
This is the 40" light bar we run on our own 4Runners. The Diode Dynamics SS40 Dual-Color 40" Light Bar is engineered to deliver ultimate lighting performance with dual output modes (white and amber), customizable RGB backlight, and seamless integration with roof racks from top brands like Prinsu, Sherpa, Cali Raised, and Front Runner.
Whether you’re building out your 4th gen 4Runner or decking out your 5th gen 4Runner for serious off-road trails or weekend ski trips, this light bar gives you the output, reliability, and style your rig deserves.

Output Options Explained:

Combo/Driving: The most versatile option. A 55x20 degree rectangular beam perfect for both near- and mid-range illumination. Great for general trail riding and daily driving.
-
Spot: A tightly focused 8-degree beam that punches light far down the trail. Ideal for high-speed off-road use or long-range visibility.
-
Flood: A wide 70x45 degree beam for even coverage of campsites, work areas, or reversing. Perfect for low-speed maneuvering or area lighting.
-
SAE Fog/Wide: Meets SAE J583 standards when aimed properly. 90x10 degree horizontal spread with minimal upward scatter — legal for road use in most states.
