GTR Lighting V.4 Yellow LED Fog Light Bulbs

Enhance your visibility in rain, fog, and snow with the GTR Lighting V.4 Yellow LED Fog Light Bulbs. Producing a vibrant yellow output while delivering the same impressive 3,600 lumens per bulb as the standard V.4 series, these premium LED fog light bulbs combine exceptional brightness, precise beam control, and OEM-level compatibility in a compact, plug-and-play design.

High-Performance Yellow Output

Unlike standard white fog lights, the V.4 Yellow bulbs emit a rich yellow beam that improves contrast and reduces glare in poor weather conditions. With 3,600 lumens of output per bulb, you'll enjoy significantly improved visibility without sacrificing beam accuracy or creating excessive glare for oncoming traffic.

Advanced LED Chip Technology

The V.4 Yellow series utilizes custom NLW1860CV2 multi-core LED chips, based on CREE XD14 technology, designed to closely replicate the position of a traditional halogen filament.

Instead of stacking multiple individual LED chips together, these bulbs feature a continuous crystal design with virtually no gaps between the emitters, resulting in:

• Precise OEM-style beam patterns
• Improved light focus
• Reduced glare
• Excellent performance in both projector and reflector fog light housings

This innovative design allows the V.4 to deliver exceptional brightness while maintaining proper beam control.

Intelligent Thermal Management

Powerful LED performance requires effective cooling, and the V.4 is engineered to operate reliably under demanding conditions.

Each bulb features:

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

The integrated thermal protection system continuously monitors operating temperatures. If the cooling system becomes compromised, the bulb automatically reduces output to protect the internal components while still providing safe, usable illumination.

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

Compact Design for Easy Installation

Unlike many actively cooled LED bulbs, the V.4 is designed to fit where other bulbs cannot.

Features include:

• Low-profile mounting depth of approximately 20–25 mm (depending on bulb type)
• Compact 39 mm heat sink and fan diameter
• Slim external driver
• Compatible with most factory dust covers

Its compact dimensions make installation simple, even in vehicles with limited space behind the fog light housing.

Built-In CANBUS Compatibility

Many modern vehicles monitor lighting systems using CANBUS or PWM technology, which can cause inferior LED bulbs to flicker, display dashboard warnings, or fail altogether.

The V.4 Yellow includes an integrated CANBUS driver that helps eliminate:

• Flickering
• Pulsing
• Bulb-out warnings
• Dashboard error messages
• Unexpected shutdowns

Most installations require no external resistors or anti-flicker modules, making the V.4 a true plug-and-play upgrade. While a separate PWM module may still be required for a small number of applications, the vast majority of vehicles are fully supported.

Intelligent Voltage Protection

The V.4 intelligently manages voltage variations to protect the LEDs and ensure reliable operation.

• Gradually dims as input voltage decreases
• Automatically shuts 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

Built for Better Visibility

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

• 3,600 lumens of bright yellow output per bulb
• Improved visibility in fog, rain, and snow
• Wider, more uniform beam pattern
• Longer service life
• Modern LED performance with OEM-quality beam control
