GTR Lighting PWM Interface Modules
Eliminate Flickering & Bulb-Out Warnings
The GTR Lighting PWM Interface Modules are the ultimate solution for integrating aftermarket LED headlight bulbs or 35W HID ballasts into modern vehicles equipped with Pulse Width Modulation (PWM) systems. Designed to ensure smooth operation, these modules prevent annoying flickering and error messages while delivering reliable performance.
Why PWM Matters
Many newer vehicles use PWM (Pulse Width Modulation) to control lighting systems. This allows features like halogen bulb dimming and reduced electrical load on the alternator/battery. However, PWM systems often conflict with aftermarket LED and HID upgrades, causing flickering, errors, or lights that won’t operate correctly.
Common vehicles using PWM include:
-
Dodge Ram trucks (2009+) – headlights and sometimes fog lights
-
Jeep Wrangler models
-
Ford Focus
-
Chevrolet trucks (newer models)
-
And many more modern vehicles
Plug-and-Play Compatibility
These modules are specifically designed to work with 35W HID or LED headlight/fog light upgrades in PWM-equipped vehicles. Simply plug the PWM module into your vehicle’s headlight connector (adapter may be required), and then connect the other end into your relay harness trigger input or directly into your new headlight system.
