Most vintage British motorcycles including Triumph, BSA, Norton and Matchless (just to name a few) from 1950s through the 1980s used wire clips to secure and attach the headlight lens to the headlight rim or bezel.

Wire clips are among the simplest design that works but often times gets confusing when removing and reinstalling.

Headlight wire clips are also refereed to as "fixing clips".

Part numbers

The headlight wire clips fitted on vintage British motorcycles where originally produced by Lucas, the same manufacture that produced the majority of electrical components on vintage British motorcycles.

    I suppose that growing up with the Lucas headlights/ technology it always seemed so simple to separate the headlight from the rim. First time after an sliding on black ice accident and damaged rim in 1966?.

    Great video for people new to old style fittings and simple technology though. Short and to the point.
