Review on DASPARTS Brake Light Switch, 2 Prong for VW Beetle, Ghia, Type 3, Bus 54-67, Vanagon by Tyson Mosucka

A switch popped up and went to screw into my brake connector but it only went halfway. I quickly noticed that the thread is conical, not straight. It turns out it's 1/8" NPT, which is SUPER close to an M10x1.0 thread. In fact, the difference in pitch and diameter is only a few thousandths. The killer thing is that it's a tapered thread. The Switches are there After some time of research I found out that you can only get a genuine M10 brake switch on BMW motorcycles BMW part number: 61311244334.
