H4 conversion question

I'm sure this has been asked a million times, but after hours of searching I can't seem to find anyone with the same problem. Here's the deal: I've installed actual HID low beams(ones with the ballast) and H4's in the high beams. When I switch to the High Beams, they are really dim and yellow. Its my understanding that they are not receiving enough wattage. I believe they are the 55/65w style. Are there relay kits to correct this? My low beams work perfectly BTW.

Re: H4 conversion question

take a look over at this thread to double check your wiring; you may just need to switch a couple of pins around:

Re: H4 conversion question

Where did you get your HID kit from and do you have any links of the car with them installed?
