well im new to the site but i have had h.i.d. lights on all my vehicles and had no problems. i have an 03 eddie bauer with low and fog hids with the realy and auto lights and have no problems even when i turn the truck on right away. i have the relay harness for the lows and the fogs and the light output is amazing. i figure as long as you use the realy harness you will be in good condition.
