Powerbronze used to sell coloured headlight protectors, although as you say, illegal in the UK. I had an amber one for my Fireblade in the late 90’s early 2000’s, to use abroad. Sometimes there’d be as many as sixteen of us going down to the Bol d’Or, so by me riding at the back, the leader of the group knew we were all present if he could see the amber headlight. Worked a treat.
