great gimmick. shines brightly and can be perfectly eg to bicycle handlebars or similar fix. is the skulls activated by pressure on the nose. eyes light up really bright, with the second nose print an ingenious color-changing effect. to be seen and all worth the money as a gimmick. have the product already ordered 3x. also great for gift giving suitable. actually would be young and old on such a fuss. Of course replace the product no bicycle lights, but is only gimmick. quali is super.
