Ligths Flickering When Driving.

[kizerboy]

Hi everyone. This is my first post here so please bare with me. Sometime ago I thought I saw a topic/ bulletin on flickering light on the 2008 gmc sierra. Whats happening is while driving at night with the lighting system on if you activate the turn signal the lights will pulse with the flasher.Stepping on the brakes, using the intermittent wipers all will cause pulsing of the headlights. Anyone know about this issue or if there are any discussions on this as it is in the dealership and they say they can't seem to find anything. Any help would be much appreciated. Thanks.

+1 on the %#@!%# bit. Drives me nuts. I was wondering though if doing the Big3 would help with this.

 

By the way welcome

sounds like a bad ground issue

My headlights flicker when the TCS engages... I am assuming this is normal?

so does mine, when i brake, but especially when i roll up the windows. i figured it was the battery, since its the original.

i have the same issue with my 06 sierra. ive got hids in it and i notice it more with those than with the halogens, ive even gone as far as using a relay kit with my hids to get power straight from the battery and it still does it. annoying as hell
