GTR Lighting V.4 LED Fog Light Bulbs

Upgrade your vehicle's fog lights with the GTR Lighting V.4 LED Fog Light Bulbs, engineered to deliver exceptional brightness, precise beam control, and outstanding reliability. Featuring advanced CREE-based LED technology, intelligent thermal management, and integrated CANBUS compatibility, the V.4 series provides a true plug-and-play upgrade for drivers seeking improved visibility and a modern, cool white appearance.

Advanced LED Chip Technology

The V.4 utilizes custom NLW1860CV2 multi-core LED chips, based on CREE XD14 technology, to closely replicate the position of a traditional halogen filament. Unlike conventional LED bulbs that use multiple stacked LED chips, the V.4 features a continuous LED crystal with virtually no gaps between emitters.

This innovative design delivers:

• Superior beam pattern accuracy
• Improved light focus
• Reduced glare
• Excellent performance in both projector and reflector fog light housings

The result is significantly more usable light while maintaining the precise beam pattern your factory housing was designed to produce.

Intelligent Cooling System

Built for long-lasting performance, the V.4 features a premium cooling system designed to keep the LEDs operating at peak efficiency.

Each bulb includes:

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

An advanced thermal protection system continuously monitors operating temperatures. If the cooling fan slows or stops, the bulb automatically reduces its output to protect the LEDs while still providing safe illumination.

The integrated smart driver also adjusts fan speed automatically, maximizing cooling performance while minimizing operating noise.

Compact Design

Unlike many actively cooled LED bulbs, the V.4 is designed to fit inside tight factory fog light housings.

Features include:

• Approximately 20–25 mm mounting depth (depending on bulb type)
• Compact 39 mm heat sink and cooling fan
• Slim external LED driver
• Compatible with most factory dust covers

This compact design allows installation in vehicles where larger LED bulbs simply won't fit.

Integrated CANBUS Compatibility

Modern vehicles often use CANBUS and PWM systems to monitor factory lighting. Many aftermarket LED bulbs can cause flickering, dashboard warnings, or intermittent operation.

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

• Bulb-out warning messages
• Dashboard errors
• Flickering
• Pulsing
• Unexpected shutoffs

Most vehicles require no additional resistors or anti-flicker modules, making installation quick and hassle-free. While a separate PWM module may still be necessary on a small number of applications, the V.4 works flawlessly on the vast majority of today's vehicles.

Smart Voltage Management

The V.4 intelligently manages varying input voltages to ensure reliable operation and protect internal components.

• Gradually dims as 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

Brighter Visibility

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

• Up to 6 times more usable light output
• Crisp cool white illumination
• Longer forward visibility
• Wider beam coverage
• Improved nighttime driving confidence
• Longer service life

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

Features

• Custom NLW1860CV2 LED chips based on CREE XD14 technology
• Filament-style LED design for OEM-quality beam patterns
• Bright cool white output
• Up to 6x brighter than factory halogen bulbs
• Aircraft-grade 6063 aluminum housing
• Waterproof dual ball-bearing cooling fan
• Intelligent thermal protection system
