Scotty Mac, it says that it doesn't work unfortunately.
I have not seen a post saying that the effects work on the bridge, that the bridge either lights up or it doesn't. Past that, look through the SLI bridge forum post and as far as I remember, you see the exact same thing.
P. S. That topic is 32 pages long. If you don't want to read through, then you may not get the answers. If you do, I can almost bet that every answer is in there.
