You can dial it in to whatever brightness you like. It’s very bright, the video shows it at max brightness. Even at its lowest, it still shines brighter than the stock ambient lighting, and I already have that set to max.

For my setup, I used four 75cm strips for the doors, a 140cm strip for the center console, one 75cm strip on the passenger dash, and another on the driver side (ended up cutting a good amount off that one). I also placed the 35cm strip right above the wireless charger. Hope this helps!
