Cartek battery isolation switch safety stickers, a handy pack of two isolator switch identification stickers, one large for the external switch and a smaller one for internal dashboard use. These stickers are required for most motorsport events and help ensure scrutineers or marshalls push the right switch.
A good idea to keep some spares handy, avoid cleaning the stickers with any kind of cleaning products that might remove the print, cutting polish etc.
