Breakers don't blow, they trip. Do you mean a fuse? If you are talking about a breaker, you can reset it. Wether it was a breaker tripping or a fuse blowing from installing a new bulb, if the light switch was on when you installed the bulb you got an initial surge from the immediate completion of the circuit. The only thing to be cautious about is a possible fault in the light bulb base. See if the new bulb lasts or if it burns out quickly, you might have a short in the light fixture which needs to be addressed because it could be a fire/electrical hazard.

If the bulb is a "bayonet cap" bulb there are two contact pads on the base of the bulb and two barbs protruding from the sides. When the bulb is first inserted, before twisting to lock, the bulb contact pads can bridge the live contacts on some light fittings and short the circuit, causing the breaker to trip.

Always turn the light switch off when changing a bulb (usually the up position). If you are not sure where "off" is then turn the light circuit off at the breaker and use a table lamp for ambient light.

Can a 220 circuit breaker run a 120 light bulb?

Yes. The 125V is the rating of the bulb, which indicates the voltage it was manufactured to withstand. The voltage it is actually operated at does not have to be precisely 125V; As a matter of fact the voltage coming from your wall socket can vary from as low as 100VAC all the way to above 125 VAC. So, screw that bulb in and light up your world!
