I purchased this from a Germany eBay seller for $90 shipped. It is pretty cool. You can manually operate the spoiler from the
switch which installs on the dash and matches the other switches there. When the spoiler is down, the light is unlit. As it raises or lowers it blinks and when it is fully raised the red light stays lit.
This may seem unnecessary, but in Los Angeles you can go from under 55 MPH to over 75 MPH numerous times during a commute. With this I can easily manually raise it and when I am parking I am reminded to lower it due to the red light.
