You would have to also buy the actual foglights as well. My 2019 SR+ had dummy foglights (no LED strip or LED light). I replaced them and tried to get TESLA mobile service to activate the on screen foglight toggle but they said that they could but within days it would probably disappear since my car wasn't supposed to have foglights. So I ended up just hardwiring them to come on when the headlights are on. See

I would be all for the interior lights though. We know they work cause they pop on and off on occasion.
Acceleration boost would be pretty sweet as well.
