I found a solution to the operation of the $250 Tesla OEM accessories illuminated doors sills, front only. It seems the size of the magnet in the contact piece that comes with the sills is so small and the installation tolerance so minute that activation success is difficult. The attached round magnets from Amazon create a much bigger area for the activation zone so chance of connection is so much greater. The magnets just stick on top of the contact point magnet that the OEM provides. The OEM magnet contact points that are placed on the bottom of the doors seem so small and their placement needs to be so precise. The much larger round magnets from Amazon provide a much greater margin for install and light activation success.
