Usually, you can tell if the fuse is blown by looking at the fuse element through the clear plastic box.

Touch each fuse connector with a multimeter lead.

What does it mean when your brake lights don’t work?

Touch each fuse connector with a multimeter lead. You should hear a beep sound if the fuse is in good condition (if you are using the Continuity setting), or close to zero Ohms (no resistance), if you are using the Ohms scale. This means your fuse is good. If you hear no beep or your meter reads infinity resistance, the fuse is no good. 4.
