The resistance of the bulb filament is very high, which means that the potential difference (voltage) across it is very high. Such, as all of the power goes to heating the filament, which makes and give off the light. In contrast of the wires have much lower resistance, so even though the current is the same. The power used in heating the wire is tiny compared to the power used in heating the filament.
I hope is helpful

The answer is in the below lines....
When electric current passes very thin high resistance filament which has very high melting point of 380 degree celcius.
Due to its very high resistance and melting point,the tungsten filament can be kept hot without melting away whereas when same electric current passes through connecting wires it produces negligible heat because of its low resistance. Electric bulb is filled with chemically unreactive gas like argon or nitrogen which reacts with hot filament and hence prolongs the life of filament.
Hope you like it....
