Diode Dynamics DD8404 SS40 Pro 40-Inch LED Light Bar White Spot Multicolor Backlight

The Diode Dynamics SS40 LED light bar is a top-tier lighting upgrade engineered for maximum performance, durability, and style. This 40-inch Pro model features white spot optics with a standard multicolor backlight (MBL), delivering exceptional long-range visibility for off-road adventures, worksites, and nighttime driving.

Key Features:

• Patented Total Internal Reflection (TIR) optics that capture and focus nearly all light output exactly where needed, without glare or wasted light
• SmartSelect technology with dual-function main beam allows you to run inner segment only, outer segments only, or the full bar without extra wiring or switches
• Selectable multicolor backlight in your choice of eight colors, plus a dynamic startup sequence
• Rugged aluminum housing with ASTM-certified powder coat finish and IP69K waterproof rating
• Pro power level provides a noticeable boost in output over Sport models
• Uses 6000K Cool White LED emitters with swappable lenses for easy optic and color changes
• Constructed with aluminum PCB, copper PCB, polycarbonate lens, aluminum heatsink, and stainless steel brackets

Unlike reflectors, TIR optics capture and focus nearly all of the light output, shining it only where you need it. Thanks to copper circuit boards, thermal transfer materials, and optimized heatsinks, this light bar effectively dissipates heat from the LED chips, allowing them to run at maximum power. Extensively tested for long-term operation from -40 to 185 degrees F, along with vibration, moisture intrusion, and corrosion testing to SAE standards.

Made in USA with global materials and backed by a Limited Lifetime Warranty. Whether you're lighting up trails, navigating dark terrain, or illuminating a worksite, the SS40 Pro delivers professional-grade performance with modern style.
