From observations they are available for Toyotas and the like with disk wheels but wether they are made for mags with tube nuts I am not sure.
They have been made for trucks for years.
They are part if mine spec safety regulations.

They came in a full set for four wheels with Nissan Patrol - very handy to check caravan wheels to ensure the nuts don't move. I tried to look them up on Net but could only find Mine Safety minecorp.com.au/products/wheel-nut-indicators-suit-steel-wheel/
The Nissan ones are a black cap that sits over nut with a arrow indicator.
