Just bought the Raptor Performance shift light. They have a new one out that has a launch mode. The launch mode is triggered by the VSS (vehicle speed sensor) on newer cars. When I told them I needed it to be activated by a ground (neutral safety switch) they reprogrammed it for free. They also themselves solved the problem of not activating the launch mode while shifting by programming a 2 second delay into the unit.

This is a great unit and I bought it for my mainly street car because it is fairly small.
