What will happen if this 4.5 v bulb is connected to a 1.5 v cell?

The bulb need the correct voltage to operate. Your bulb would light if it is a 1.5 volt light. So the voltage of the supply and the light must be matched. Too little voltage won't light the light, too much will light it too much and blow it up.

At 4.5 volts it will glow very brightly, but it will quickly burn out.

Why did the breaker trip when you unscrewed a burnt out bulb?
This is a condition that should not happen under normal conditions. In North America the smallest home breaker is 15 amps. If a fault current is higher that the breaker setting the breaker will trip.The only way the breaker could have tripped is, if when screwing the bulb out, the feed wires feeding the light socket turned and shorted out against each other.Turn the power feed off and thoroughly check the feed wires. Make sure that the insulation is good all the way to the terminal points.As a side note, if the circuit that the fixture is connected to is fully loaded to say 13 amps it would only take an additional 2 amps to trip the breaker. If the bulb flashed when you started turning the bulb out, this is most likely what happened.

There is a 3.75 Volt drop across each bulb.
How do you change the license plate bulb on a Toyota matrix?
Open the hatch door. Right behind the license on the inside of the door is a cover that you take off using a thin blade. This exposes the back of the bulb holder and the wire connected to it. Remove the wire by pulling on the connector that fits into the back of the bulb holder. The back of the bulb holder then needs a quarter turn counter clockwise. The best tool to use to turn the bulb holder is a 15 mm socket on an extension long enough to reach the bulb holder inside the hatch. Once you have removed the bulb holder, you can simply pull the bulb straight out of the front of the bulb holder. Replace the bulb with a #168 bulb.
