Testing wishy-washy circuits exterior lights? I have not long replaced blown bulbs on the two front exterior...

I have not long replaced blown bulbs on the two front exterior lights in the lantern on the front of my house. The lights still do not work, and near is no problem with the circuit breaker. how can i trial the wiring (visual inspection looks okay) - I own a multimeter but im not an electrician so not sure exactly where to examination.
I hope within is someone still up right...
Answers:    "im not an electrician" ... then for your own sanctuary, get an electrician contained by.
My fridge isnt getting cold and the freezer...
A multimeter usually comes with instructions, best to follow the guidance contained therein, If replacement proven bulbs do not street lamp sounds like no power to the fitting.
