I just installed a McCulloch HID kit on my 05 Sierra and love the light output compared to the silverstars I had before.

Is it normal for HIDs when they are first turned on to be a little dim and brighten up after about 5 seconds?

 

Yes, very normal. Mine do the same thing. I have McCulloch 4300K.

 

Cool thanks,
I have the 4300K too and love them think I'll do my fog lights next.

 

Mine do the same thing, brighten up a little. Its like a fluorescent light in cold weather. Takes a while to "heat" up.

yep, mine take about 5-6 sec when its real cold outside, i'm running 6000k, huge difference of the silverstars i had
