yeah, it was in this forum... He also has pics of his accord in the sticky. I think it's on the last page or page before. He's the one that has pics of some tail lights that have Halos on them. He made them himself.
4 projectors all aimed at the same level would be hella bright, and hella hot (temperature wise)
Make sure you dont go for like 8K bulbs... The blue light is a lot more straining on the eyes, and with 4 of them on... you wouldn't want to be driving for too long at night. You would need to go for a more natural sunlight color temp.
Definately expensive to do though... you really want to put over $1K into your headlights?
