GTR Lighting V.4 Yellow LED Fog Light Bulbs

Designed for drivers who demand superior visibility in adverse weather, the GTR Lighting V.4 Yellow LED Fog Light Bulbs combine a powerful 3,600-lumen yellow output with advanced LED technology, exceptional beam control, and OEM-level compatibility. Whether you're driving through fog, rain, or snow, these premium LED bulbs deliver outstanding performance while maintaining a precise, glare-free beam pattern.

Powerful Yellow Performance

The V.4 Yellow bulbs produce the same impressive 3,600 lumens per bulb as the standard V.4 model, but with a vibrant yellow light that enhances contrast and improves visibility in challenging weather conditions.

Benefits of the yellow output include:

• Improved visibility in fog, rain, and snow
• Reduced glare and backscatter
• Better road contrast
• Modern performance with classic fog light functionality

Advanced LED Chip Technology

At the heart of the V.4 is a custom NLW1860CV2 multi-core LED chip, based on CREE XD14 technology. Unlike conventional LED bulbs that stack multiple chips together, the V.4 utilizes a continuous LED crystal that closely mimics the position of a traditional halogen filament.

This innovative design provides:

• OEM-style beam pattern
• Superior beam accuracy
• Excellent focus
• Reduced glare
• Outstanding performance in both reflector and projector fog light housings

Intelligent Thermal Management

To ensure maximum reliability, each V.4 bulb is built with a premium cooling system featuring:

• Aircraft-grade 6063 aluminum construction
• Excellent heat dissipation
• Corrosion-resistant housing
• Waterproof high-speed dual ball-bearing cooling fan

The intelligent thermal management system constantly monitors operating temperatures. If excessive heat is detected or the cooling fan becomes compromised, the bulb automatically reduces its output to protect the LEDs while continuing to provide safe illumination.

A smart cooling controller also adjusts the fan speed automatically, minimizing operating noise while maintaining optimal performance.

Compact Design

Despite its advanced active cooling system, the V.4 maintains a compact footprint that fits where many competing LED bulbs cannot.

Features include:

• Approximately 20–25 mm mounting depth (depending on bulb size)
• Slim 39 mm heat sink and cooling fan
• Compact external LED driver
• Fits most factory fog light housings and dust covers

Its space-saving design makes installation simple on a wide range of vehicles.

Built-In CANBUS Compatibility

Many modern vehicles use CANBUS or PWM systems that can cause aftermarket LED bulbs to flicker, display warning messages, or fail to operate correctly.

The V.4 includes integrated CANBUS circuitry that helps eliminate:

• Dashboard warning lights
• Bulb-out errors
• Flickering
• Pulsing
• Unexpected shutdowns

For most vehicles, no additional resistors or anti-flicker modules are required. While certain specialized applications may still require a PWM module, the V.4 provides true plug-and-play compatibility for the vast majority of vehicles.

Intelligent Voltage Management

The V.4 is engineered to safely operate across varying input voltages.

• Gradually reduces brightness as voltage decreases
• Automatically turns off below approximately 8V DC
• Compatible with most 12V PWM daytime running light systems
• DRL systems operating below 8V DC will not illuminate the bulbs

This intelligent protection helps maximize LED lifespan while ensuring dependable performance.

Superior Visibility

Compared to factory halogen fog light bulbs, the GTR Lighting V.4 Yellow offers:

• 3,600 lumens of bright yellow output per bulb
• Up to 6x more usable light
• Increased forward visibility
• Wider beam coverage
• Improved performance in poor weather
• Long-lasting LED reliability

Available in virtually every popular bulb size—including 9005, 9006, H4, H11, H13, and many more—the V.4 is a direct replacement for most factory fog light applications.
