Is a two, three our four sided bulb the best and what color works best? I have a 2014 XF7000 and no need for a rectifier. I am thinking 5500K to 6000K is the best color. My main complaint is the low beam is too low and the high beam is too high. It would be great to fill in the gap. Anything over 35 MPH is over-driving low beams and highs are in the trees. I only turn the highs on when approaching hills. Anyone have a picture of Tomcats bulbs that shows the LED layout?
