HID's dim in RSX?

I have now installed several HID kits in my RSX over the years and they have both been very dim. Either on par with non-HID or slightly less bright than my OEM headlights. Thing is, my friend had the same brand of HID's installed on his Civic and they're WAY brighter in his civic than they are on my RSX. Any idea how to get the full brightness from HIDs in an RSX? :rest
