Do these ballast accept the Phillips Ultinon Bulbs? If so I am definaley in for another set.
I love the 6000K bulbs, but the slight purpleish hue from the Phillips Ultinon Bulbs would color coordinate better.
Unfortunately I can't answer that question accurately since I do not sell the Phillips bulbs nor ballasts. However, it might be a possibility.
Why don't you go with a higher K number or if you want like a violet type color, I can get Violet bulbs as well.
In fact, for women riders, if you'd like, I can get pink color bulbs with your kits.
