I donít own a Forester, but.......
Being that you mention itís on a 2017 Forester, Iím guessing youíre not the original owner?
So......being a switch just to turn on a red light probably isnít exciting enough.
Iím betting youíre going to be told by others itís an aftermarket switch that was installed by the previous owner, so no one except that person that installed it is going to know.
