Fit 2007 - the front and rear lights start flickering from time to time.
Some people said it was the alternator, others corrosion in a harness or a fuse.
It was a HEADLIGHT SWITCH recall for some cars of 2007-08 - my car is not among these.
Please share your experience.

 

Are your interior lights flickering as well? Sounds like the alternator to me. Have you tested it?

 

I just got my fit not too long ago and that's one of the first things I've noticed. Mines doesn't flicker all the time though. I've looked into it and found that it's a common issue so I just left it.
