I found a sequential taillight for the 01-03 f4i. It comes in smoked and clear that I've seen so far. The brake pattern also looks kind of cool.

$90!! Ouch!

I'm just not a big fan of the integrated lights. But this is a personal opinion and your bike. As long as you like it that's what matters. Just remember, with this light you do not have red reflectors at the rear so you'll need to add those.

 

My bike is probably more lit up from the rear than anyone else on here lol :P
I've got CRAZY bright passenger peg lights, a knight rider led bar on my plate, license plate bolt lights, brake light, and a diamond grade reflective vinyl band on my helmet.

 

This is my bike
