If not the fuses in both box's then check the ign. switch at the key.
... whats a charm crown?

Check your fuses - then the bulbs themselves. Normally its one of those. Since all 4 went out, I'm assuming its probably a fuse. The flasher ,under the dashboard needs to be replaced.On older cars its a 552 flasher.Auto part stores know this part.
replace flaser can in fuse box
hazards can- be natural or human caused
there broke there broke
Don't know what your asking? were/ what does it do, better yet whats the problem
its most likely the flasher unit they are cheap and fairly easy to change
They are a compleat circuit if one light is bad it will not work
Analog signals are continuous while digital signals are discrete
bring for them a bunch of flowers and a crown
whats it worth never open
