A shunt member includes an insulation sheath, a first lead wire having a shunt wire engaging section located in the insulation sheath, a second lead wire having a shunt wire engaging section located in the insulation sheath and adjacent to the shunt wire engaging section of the first lead wire. A shunt wire is connected between the shunt wire engaging sections of the first lead wire and the second lead wire for forming a shunt circuit of the bulb. When the shunt member is received in the lamp holder, the shunt member and the filament of the lamp are connected in parallel. An insulation bead member is further fixedly mounted between the shunt wire engaging sections of the first lead wire and the second lead wire for keeping a fixed distance therebetween.
