Review on Directed Electronics 8600 Magnetic Switch by Chad Judex

On the one hand it works exactly as advertised and works well. Has a long (unfortunately thin) wire that allows for more installation flexibility. On the other hand, I had to supplement the inner magnet with a pair of neodymium round magnets which I super-glued onto the device and then spray-taped with tape to protect and hide (see photo on the left side of the tailgate). I also padded the tape with extra high grip double sided tape (VHB) to make sure it wouldn't come loose. It may not be necessary, but it's a good idea for a few bucks. Used together with night lights and switches; With this you can wire a switch so the light is 'always on', but only when the tailgate is open. When closed, the circuit breaks and the light turns off without draining the battery. Works great. Tons of tutorials on YouTube to help you adapt to your needs.
