Need some help Ladies and Gents. 2013 RT+ with 6,000 miles. Under warranty. My headlights dim and get Bright with acceleration and brake. I have checked the pulleys and don't see anything. Any help would be appreciated. Mess with it or take it to dealer for warranty work?

Thanks guys. This is going to sound crazy but the lights get brighter when I hit the brakes. I have searched everywhere looking for an answer. I am so confused.
Blasting Bobs Reso Deletes. K&N Filter. CAI. Diablo Tuner. New Thermostat. New catch can. Replaced interior lights with LED's. These are My MODS and I don't believe any of these would cause this. Take it to the dealer????

Not crazy, just the nature of the beast. I installed Mopar sequentials and it is more pronounced yet. You can have them change batteries and alternators and it will still be there. It's just the way the system works when compensating for a load.

Same thing on my 2010 R/T. I know this will not make you feel better but there is a ton of others out there with the same problem. I just tell everyone that's it's a safety device warning others (on-coming traffic) that you are on the brakes.

I did fix mine by changing over to a HID kit, they are powered separately. The only problem I have now is running them with the switchback's it looks like I'm running brights all the time with those 4 white lights staring at ya.
