There are several possibilities:
- Burnt out light, but you apparently have already tried a new bulb which you knew for certain to be good.
- Sometimes porch lights have both a switch and a photoelectric eye. The electric eye could have gone bad, or maybe you just tried to turn it on in the daytime.
- The switch could have gone bad, or a connection to it failed.
- The fixture could have gone bad, or a connection to it failed.
- The circuit breaker could have tripped.
- The light might be on a GFCI and the GFCI might have tripped.
- Someone could have put a nail into the wire when hanging a picture or installing new siding.
