Couple of small conerns
 

I have a 2005 XG350L it will be a year old next month and has 6300 miles. I
dont drive much at night but had to last night and noticed that with the
headlights on and the air conditoner running ( climate control ) that
everytime the air kicked on the lights would dim....is this normal, I dont
remember my wifes Santa Fe or our Tucson ever doing it, I could be wrong and
just happened to notice this one. Second concern is when breaking I get a
slight pulsation in the break pedal between 20 and 30 MPH noting above that
or nothing below that. I can see the rotors though the wheels ( custom
wheels ) and they look perfect no ridges ,scatches ECT. front or rear. Any
suggestions
