Hate replying to an old Thread, But i found limited resources on the matter. so ill just leave this here for future reference.
I have just put leds in my 33. and long story short, they are no good.
although very bright, the light scatters much to quickly without the aid of a projector, so basically the lights hurt your eyes to look at but dont illuminate much of the road.
also making to h1 clip fit around the cooling fans on the back of most leds was a nightmare, and the cap on the rear of the headlight housing wont fit them either,
puting standard bulbs back in tomorrow.
cheers
