Product Details

PWM Harness: Built by GTR Lighting Specifically for systems with Pulsed Width Modulation, this bespoke module features smart internal circuitry built to combat bulb out warnings and flickering that are all too common when upgrading from a halogen bulb to LED or HID lights.

Installation: This couldn't get much easier. Just plug in the module into the vehicle headlight connector (adapter may be required) and plug the other end into your relay harness trigger input, or directly into the new HID or LED headlight system.

HID - 35w Only: When used with HID systems, this module is specifically intended for 35w applications only.

I had bought the GTR lighting PWM interface Module just incase if I would need it for my 2014 GMC Sierra.
When I installed my GTR Ultra 2 LED thay worked for a few seconds
and went out. I installed the PWM and the light came on and been work just fine.

After purchasing led headlights at a local parts place and having light issues they could not help me fix I found this site and asked why headlights keep cutting out. Had my answer the next morning and order parts. Headlights now stay on as they should.
Thanks for the quick response time and getting my parts shipped out fast.
Highly recommend you guys

These lights are definitely amazing!!!! The lights brightness, color and quality are comparable to factory hid systems. I've struggled for a long time to find a led light that's as bright as hid for my 2014 grand Cherokee. They were super easy to install however, they did need a little adjustment for the proper beam pattern. If you're even a little mechanically inclined you shouldn't have a issue lining them up. I haven't had them long so not sure if they'll last long, fortunately they come with life time warranty so I'm not worried if they don't. All in all, so far they are definitely worth the hefty price tag...

DRL interface

Joseph Latessa

These for my 2013 Accord .
They reduced the lumens from full high beam, but are still a little too bright for my liking (and oncoming drivers) to be a proper DRL
