Oh, interesting. Mine don't do that either. I've just noticed the light output on the ground from driver side is a little less bright than my passenger side, and sometimes its color changes. I've seen the light output on the ground be more yellowish, and sometimes more purpleish. From outside (looking at the headlight) the color doesn't change. I have no idea what it is that could be doing it. All I know it'* one of the ballasts I got from Brian when I bought my retro'd lights that I used when the DDM ballast kept blowing bulbs. But, I can get a whole new digital set from DDM for only $55 so I think I might just do that.
Hey wasn't that ballast suppose to come back to me after you got your DDM replacement? I still have the 2nd one that goes with that Xentec lol.
