A fuse always blows for excessive current. Either the device it is protecting is going bad and drawing excessive current, or you have a short in the wiring (or device).
Are you using the right value of fuse ? If this involves your brake lights or turn signals, it could be the bulb itself. Quite often the filaments short internally inside the bulb when they blow, and short the brake wiring to the turn signal wiring. Check for a bulb with a white residue inside it. If you find one, replace it. It will probably have two contacts in the base, one for each filament.

What would cause your fuse to blow when you turn on your lights on your 1993 Mazda 323 the fuse to the tail lights on dash lights blow?
I'm not sure I understand your question. I can't tell if you have one or two different fuses "blowing." The only thing which causes fuses to "blow" is a short circuit condition in the circuit which the fuse protects. IF you have two different circuits blowing fuses, then you have at least two short circuit faults. j3h
