I have a 2005 civic that is having intermittent headlight /driving lights dimming /flickering . Some mornings it does not do it and then it will for several days. It may do it for several miles or just for a short time. I did however notice this morning that when I put my power window up it dimmed the driving lights. I have a new battery and have checked grounds. I did however install a new radio just in case anyone asks , but it was doing it prior to the aftermarket radio installation. Does anyone have any suggestions as this is rather annoying.

 

How is your alternator?

 

Thanks was thinking about the alternator. I will have that checked .

 

Thanks had alternator changed on Friday and lights are working great no more flickering.
