Piaa super plasma's are $60 and have a higher color temp. than Silverstar, so they give you a more blue color, and they also provide MORE light ahead of the car, but less on your car sides. Either or, you may love the way your bulbs look, green, blue, purple, whatever.....they will suck during bad weather. Yellow is the ideal color that pierces though bad weather, which is why stock bulbs have that ugly yellow color. Beleive it or not, Honda bulbs are very efficient...but who wants stock? :exnbp:
