This is a very simple solution for the poor interior lights in the Model 3. Just add one. No rewiring or splicing necessary. Detach the right side center console panel. Locate the existing plug with a white and brown wires which connects the LED from the inside of the center console to power. Unplug that and connect this LED in. Attach the LED with the included double sided tape to the underside of the display mount. Reinstall the side panel and you are done.
