Thanks for the chart. Based on it, wouldn't it be better to stay with stock bulbs? I had always thought staying closer to the clear white spectrum is the best option for best visibility/illumination, even though the blue headlights are in style? Or am I wrong on this one? Also, if I wanted to stay with stock (or similar to) bulbs, are there any good aftermarket xenon bulbs available, or is it best to stick with true OEM bulbs?
