Where are ya'll getting you HID kits from?
:stupid:Then they aren't HID.
HID's only have a single wattage ballast.
The only halogens I've seen are 55w low 60w high. That is why HID's are popular because they only pull 35w and give more light.
If you get a hi/low HID kit it doesn't change the brightness or power any, it just activates a little solenoid on the back of the bulb to tilt the bulb in the housing to reflect it upwards to see more.
