i've recently put in yellow bulbs for my fog lights. looking at the lights themselves you can't tell they're yellow. but when it gets dark man alive the light on the road is yellow (but still looking at the bulbs still don't look all that yellow).
i know that yellow is supposed to be more safe because of the light temp, but i'm still torn on how it looks. too jdm for a european car? (although, it was the europeans that started the whole yellow light thing).
