Gutted ! #Mac1 can no longer get the small narrow rear reflectors. Sad times

Anyone got a suggestion for something similar thats IVA proof? (other than the std CBS type stuff)

Just cut up a larger one?

That's a bugger, I'm glad I got mine when I did then.

Apparently the mac1 ones are what you would put on a car door to warn people its open.
Someone said you could get them from halfords but I couldn't see them on their website.

Mac said they had tried to get elsewhere but had no luck.

Is there a minimum size?

Pretty sure any reflector is ok,just not a triangle shape as they are for trailors
