You will need to use my 
Sensor Light blueprint. Set up the trigger, your lights and use the Ambient condition, enter in your sensor and adjust your settings. No need for night light.
Tip: If you like to take it to the next level your could set up a template sensor that has auto OFF so when you open / close the door the light will be ON for X amount of time and then turn OFF so the light isn’t always ON when the door is open, then you also use a motion sensor in the garage that will turn the light back ON or keep it ON if you are in the garage. You then use the template sensor and your motion sensor in a sensor group in the trigger. Link to the Ho To for the template sensor click here.
