Trigger wire for 12v accessories?

I'm installing underglow led kit and I was wondering if I should power it through the fuse or 12v battery. I'm trying to have it auto turn off/on with the car headlights so it will not be on all the time.

The 12V battery is the weakest link in MX. if it dies as it often does, you will be stranded. You will not be able to unlock/open the car and trying to get to the 12V battery is not easy as an ICE car as the frunk is locked and there is an elaborate procedure to open the frunk and get to the 12V battery to try and jump start the 12V battery to unlock the car. There are a few youtube videos on how to open the frunk and get to the 12V battery, may be you would like to watch the videos and then take an informed decision.
