Has anyone had any issues at IVA with a fog light mounted to their roll bar?

I've positioned mine there, and it meets the positional and visibility requirements as far as I can tell. It's not an arrangement I've seen before though, so I'm wondering if I've missed something in the IVA regs which prohibits this!

My car is PRE IVA, as on the road before it SVA/IVA came out, but my fog light, which is also the third and high level brake light is on the roll bar, at the top,

Its a high brake light for most occasions, but with a diode, its a fog light when required

but as said, my car is pre modern rules

As long as it's not higher than 1m.
