GTR PWM Interface Modules

The GTR Lighting PWM Anti-Flicker Modules are designed to eliminate flickering, bulb-out warnings, and inconsistent operation when installing LED headlight bulbs or 35W HID conversion kits on vehicles equipped with Pulse Width Modulation (PWM) headlight systems. These modules ensure a stable power signal, allowing your aftermarket lighting upgrades to perform reliably without triggering vehicle errors.

Each kit includes two PWM modules, providing complete support for both driver and passenger side headlights.

Eliminates Flickering and Warning Messages

Many modern vehicles use Pulse Width Modulation (PWM) to control headlight brightness and reduce electrical load on the charging system. While this technology works perfectly with factory halogen bulbs, it can cause aftermarket LED bulbs and HID ballasts to flicker, flash, fail to ignite properly, or trigger bulb-out warning messages.

The GTR Lighting PWM modules filter and stabilize the factory PWM signal, delivering a clean, consistent power source for your upgraded lighting system.

Compatible with LED and HID Systems

These modules are compatible with:

• 35W HID Conversion Kits
• LED Headlight Bulbs
• LED Fog Light Bulbs
• HID Fog Light Kits

They can be installed between the factory headlight connector and your HID relay harness trigger input or connected directly to compatible LED or HID lighting systems.

Designed for PWM-Controlled Vehicles

PWM headlight systems are commonly found on many late-model vehicles, including:

• Dodge Ram (2009+)
• Jeep Wrangler
• Ford Focus
• Chevrolet Trucks
• Many other modern domestic and import vehicles

Some vehicles also use PWM technology to control fog lights, reverse lights, and other exterior lighting, making these modules an excellent solution for a wide range of lighting upgrades.

Quick Plug-and-Play Installation

Installation is fast and requires no cutting or splicing. Simply connect the PWM module between your vehicle's factory headlight connector and your HID relay harness or LED headlight system. In some applications, a vehicle-specific adapter may be required.
