Custom LED tail lights ?

[MZ 500]

I found this circuit http://www.redcircuits.com/Page105.htm I think it is what you are looking for. It says that you can drive up to 16 clusters. The 12 LEDs together are a single cluster. I would lay it all out to see how many clusters it would take to to fill in the center section. More IC's can be added if more clusters are needed. I would use two circuits one for each side.

That looks like it would work it says the lights will stay on when the brakes are applied I kind of want them to go out but the main thing was I didn't want them to keep going though the sequence I think that would bug people.

Thanks of the link there is a lot of other cool things there to.
