Tapping into a switched fuse for grill lights

Hi, I am a newbie to this forum. I have a 2018 Tundra SR5 crewcab (new to me). I have installed LED grill lights for extra visibility on Texas back roads. The right side of the fuse box is shown below. I would like to add-a-fuse to a fuse that is on when the ignition is on and off when the ignition is off. Does someone know which is the best fuse to tap into?
Thanks!

 

There is one labeled IGN which is ignition.

Positions noted on the back side of the cover. It's either a 7.5amp or 10amp fuse, cannot recall off hand.

 

That is the first 10A fuse on the top right next to the 2 blanks. Thak you for your help!

There is a thread that tells you how to tap into wires for the raptor lights.

Welcome!

 

You don’t want to tap into a fuse. The fuse is there to protect that circuit. Get a test light and find an empty slot that turns hot (light on) when ignition is turned on.

 

If you tap into an existing fuse just make certain the original fuse has enough capacity for both since the current must run thru the original fuse first.

I usually just create a new tap straight to the battery and place the fuse right at the battery. Luck.
