i didn't paint anything, i just put 65w h9 nokya hyper yellows in my stock h11 bracket (after modding the bulb). looking at my car with the light off you can't tell its yellow, but when you turn on the light it floods the street. heres a pic in my driveway to get an idea.
i have yellow fogs in my car (the same ones pictured via the link above) and i love them. they work wonders!!! and they look nice. before i got the bulbs, i just put the laminex over the lenses but it blocks some of the light, taking away from the light output. if you like the yellow look, just got the bulbs!
