tripped breaker problem

When I turn on light in master closet the light makes a pop sound and the breaker is tripped.. When I reset the breaker it lasts for several days and then the same thing happens..My house is 11 years old and the breakers are original with the house..Where should I start to determine the problem.. Should I replace the light fixture first . Replace the breaker ? The circuit is not overloaded so I know that's not the problem..


With power off look in the light and switch boxes first. What is the condition of the leads on the light? What do the wires look like? Any discoloring or bare copper spots? Could one of the wires in the switch box be touching ground occasionally? Same question at light.
