Which Size Fuse Should I Use

[ts9790147]

I have just installed new PIAA 520 ATP lights using the Tacoma factory fog lamp switch and was looking to hook the power source/spliced wire into the fuse box using a fuse tap (mini add a fuse) so that the lights can come on when the ignition is on.

I was wondering if anyone can recommend what size of fuse I should use for this type of light and setup.

Any advice would be greatly appreciated.
