My wife acquired a 2015 charger rt and we instantly noticed the headlamps were terrible compared to my 14 jeep SRT. I contacted the ONLY company I would EVER use for lighting on any vehicle I own....Xenondepot! I've used Xenondepot for over 20 years now and they are hands down the best lighting vendor out there! Anyway.....many 2015+ mopars experience many problems with hids , leds etc. when installed. These include flickering, one bulb out, not working at all etc. So Steve at Xenondepot sent me a new PWM module to test on my 2015 charger since many 15+ fca vehicle owners had problems.
HID Kit PWM HID kit Module | HID kit canceller | HID Anti-flicker module
The install was more problematic than the module...but that's for the charger forums! We have ran these for about 6 months now with 0 problems. No flicker, pulsing, bulb out warnings...nothing. Just perfectly performing hid headlights! They also match the oem led fogs pretty close. Xenondepot HIDs are hands down the best quality kits I've laid my hands on...and the PWM module is no exception! No longer needed are relays etc. No wire mess. Easy plug and play installation...and great results!
