I found a kit on ebay that I will most likely be the winner of...it's going for 450...is that good or bad? It comes with 2 D2S bulbs, 2 Hella ballasts, wires, the whole kit! What are the disadvantages of the D2S bulbs? Will it mess up my beam pattern a lot or not too much? This is the only thing I'm worried about...knowing that we should have D2R bulbs. Oh and by the way...the hella ballasts are supposedly made in Germany. Can anyone verify this?
