Bussmann(BP/ATM-A6LP-RP) ATM-LP Low Profile Fuse Assortment Kit - 6 Piece

Is the current rating on the fuse identified by number? or only by color?

Will these work on a 2018 Mazda CX-5?

Are these the micro fuses? The real tiny ones?

what rating do the fuses have? I need a 7.5 amp fuse, but would like to know what amp sizes are included for the future. thanks
