I was looking at a thread at the top of the forum "2004 - Training material & Pictures " that shows the complete details for 2004 and was wondering if anyone like my self wanted to change out the front and rear lights. Do you think they would hook up and fit the same as previous years? I am sure the probable would cost a bomb as well.

 

The lights appear to be the same shape, but you never know until you see them in person. As for price, current S2000 headlights go for around $390 a piece( that's without wire harness or grommets, just the headlight shell) and tails are about $190 a piece. I am sure the tails will run more then that for 04 with the LEDs. You also may have to do some wiring since there are a different number of lights on the car now. Good luck!
