Contrails Double?

[aerogatto]

Dear Friends
Since I started to install the new lights to my third party planes, every time that the plane hits the cold layer and contrails start to come out , strange double contrail start to go out from plane .. one contrail goes straight and the other one goes down to earth... Can somebody explain this to me and if I m doing the wrong procedure of installing this?... or perhaps its just another problem that doesnt concern the Shockwaves lights... Thanks a lot for your kind help.

I can't see how this can be related to Shockwave lights as we don't touch the contrails. You can always run the install again and select UNINSTALL, and it should leave your system in the exact state it was before installing.
