Not entirley sure if this is the right section, my 97 blazer i was wondering if i had to do any sort of extra modification for HID lights? i'll post a pic of my lights in a little bit as they are now. also I intend to drop in a set of Emergency vehicle lights similar if not exactly like the vehicles you see rolling through construction zones anything special i need to know before i drop them in?

Here's a thumbnail, taken from my cellphone
