Default Re: Crompton 60W bulb

Isn’t this the sort of bulb used on hanging fairground lights? The bulb holder is placed on the wire and makes contact via sharp points that pierce the cable. Provides a quick and easy way to add lights to a cable without having to make any joints.
I use similar bulbs of different colours on battern holders for garden illumination.
