Hi Gary,
The bulb is a simple 2 watt bayonet fitting as used in older model cars and bikes (voltage to suit your bike)
To remove the wire, once the bulb is removed you will see a slotted screw head, undo this and the remains of the old wire will fall out, push the new wire through from below, bar approx 1/4in. and splay the strands out feed it back into the recess and refit the screw
