The safest thing to do would be to call an electrician and have him check
the light fixture(s) and replace the switch.

Sometimes a ceiling or even wall mounted light fixture will create a *lot*
of heat which will damage the insulation on the wiring behind the fixture,
and this can cause a short circuit.

The circuit breaker is protecting whatever is causing this problem from
causing a fire. (Doing its job.)

I would not turn the breaker back on until an electrician has checked out
the wiring...

I had had a problem with a light switch in a walk-in closet. Turning in
on sometime did not work, so had to press it for the light to go on.
Yesterday, when I flipped it on, there was a spark. Now no light. The
light in an adjoining bathroom also went out. The breaker had tripped.
I reset the breaker and all was well for an hour or so.
When I flipped the closet switch on again, a louder spark. Again the
breaker tripped.

So what is the problem here? Could a bad switch do this? Should I just
try replacing the closet switch?
No more load on that circuit than normal.
