Has anyone noticed their headlights dim for a fraction of a second as they drive along ?

I thought it was with the a/c cutting in but in this colder weather it still does it without a/c.

Not a big deal but was curious to see if anyone else has noticed it.

 

Mine does it, but only when the the vents are set to defrost since the compressor kicks on in this mode.

 

Normal, and not as bad as older cars without solidstate voltage regulators.

 

Anytime the radiator fans kick on the lights will dim. I wouldnt worry about it.
