Diode Dynamics DD7738 Stage Series Single-Color LED Rock Light Installer Kit 4pk

Vehicle Fitment

• Universal - This kit is not vehicle-specific. Compatible with any off-road vehicle, truck, SUV, UTV, or custom build. The Rock Lights mount under the vehicle, in the wheel wells, or any undercarriage location using the included center-bolt hardware.

Fitment Notes

• Center-bolt mounting is the standard installation method included with this kit - a 3/4-inch hole must be drilled at the chosen mounting location, and the center bolt is hidden beneath the lens for a clean appearance.
• This kit does NOT include magnet mounts. Magnet mount capability is built into the rock light housing, but the magnet mount adapters themselves are sold separately. The DD7739 kit includes magnet mounts.
• This kit uses a 3-wire system: one common ground, one high-power activation wire, and one low-power activation wire. High power takes priority when both are activated simultaneously, making it compatible with two-switch factory aux setups (such as Ford Bronco or Wrangler aux switch banks).
• Rock lights are compatible with standard PWM dimmers for variable brightness control.
• The M8 barrel connector (8mm diameter) on each light makes wire routing through tight spaces straightforward while maintaining a waterproof connection.
• Snap-on replacement lenses in additional colors are available separately. The rock lights are not for on-road use.

Features

• 1,000 lm peak output (no lens) and 800 lm through the white diffused lens per rock light - significantly outperforming generic rock lights that typically operate at only 2-4 watts total.
• Dual power level system via 3-wire wiring: high-power mode draws 10+ watts (0.8A) for maximum output; low-power mode drops to 3 watts (0.2A), matching the maximum output of most competing rock lights for campsite use or battery conservation.
• Four individual TIR-style optics molded directly into each outer lens for smooth, even, wide-angle coverage - eliminating the harsh hotspots common in non-optically-designed rock lights.
• Interchangeable lens system allows color to be changed without tools - white diffused lenses are installed at the factory, with amber and red diffused sets included in the box.
• Center-bolt mounting point is hidden beneath the outer lens for a completely clean, professional appearance with no visible hardware when installed.
• Modular mounting design includes an integrated hole for optional magnet mount adapters (sold separately), supporting both permanent and temporary mounting configurations.
• Cast aluminum housing with powder coat finish and passive pin-fin heatsink provide effective thermal management for sustained high-power operation.
• IP68 waterproof-rated - fully submersible, sealed against water, mud, and high-pressure washing.
• UV-coated thick automotive-grade polycarbonate lens resists yellowing, fading, and trail impacts over time.
• Engineered and assembled in the USA, tested to SAE J575 durability standards from -40°C to 85°C, backed by Diode Dynamics' Lifetime Limited Warranty.

Product Description

The Diode Dynamics DD7738 Stage Series Single-Color LED Rock Light Installer Kit delivers everything needed to add four high-powered undercarriage rock lights to any off-road vehicle, truck, SUV, or custom build. Where competing rock lights typically run at just 2-4 total watts, each Stage Series Rock Light draws over 10 watts at full power for a peak output of 1,000 lumens bare or 800 lumens through the included white diffused lens - setting a measurably higher standard for this product category. The dual power level system adds practical flexibility: high-power mode delivers the full 10+ watt output for night driving and trail visibility, while low-power mode drops to approximately 3 watts - comparable to the maximum output of most generic rock lights - making it ideal for campsite use or battery conservation during extended trips.

The optical design is what separates the Stage Series Rock Light from cheaper alternatives. Four individual optics molded directly into the outer polycarbonate lens produce smooth, even, wide-angle 60° coverage without hotspots or dark zones - a result of actual optical engineering rather than a bare LED behind a plain lens. The lenses are interchangeable without tools: white diffused lenses come installed, with amber diffused and red diffused sets included for color versatility. Additional color options are available as separately sold replacement lenses. The 3-wire wiring system (common ground, high power, low power) makes integration with factory switch systems - including the Ford Bronco and Jeep Wrangler OEM aux switch banks - direct and straightforward, with high power taking priority whenever both wires are activated.

The center-bolt mounting hardware included in DD7738 creates a secure, clean installation with the mounting bolt hidden beneath the lens - no visible fasteners. The rock light housing also includes an integrated recess for optional N42 magnet mount adapters (sold separately as an accessory, included in DD7739), allowing a hybrid permanent/removable setup on metal surfaces. At IP68 waterproof with an aluminum housing, pin-fin heatsink, and UV-coated polycarbonate lens, these lights are engineered to withstand mud, submersion, high-pressure washing, and trail abuse long-term. Assembled in the USA, tested to SAE J575 standards, and backed by Diode Dynamics' Lifetime Limited Warranty, the DD7738 is the highest-performing four-pack rock light kit available for universal off-road installation.
