headlights dimming

[Greggles_VS]

Just noticed the other day when I put my electric windows up (probably all ve are electric I dunno) my headlights dim. Is this normal and if not what could it be due to? Still under warranty so if something is wrong I want to get it asap

It's normal for the lights to dim when the windows reach the top as more load is been applied but if there dimming while there going up could mean the battery is on its way out how old is your battery the ve is very sensitive with battery's

Get a reputable Auto Electrician to perform a 'load test' of your battery. The only real way to identify if it's on the way out.

I got a new battery about 3 months ago about 30% more cca then the original and my headlights still dim, more so when I have my Stereo past 10, but that might have something to do with the amp powering 2 80 rms speakers and a sub.
