McGrath lights

Hi everyone.
I'm chasing some info on McGrath trailer lights please. Rubber mounted with round lens.
There seem to be different sizes. One type is about 6"diameter and the other one about 4" diameter.
Which ones are correct please.
Regards

Thanks but i was wanting to know the diameter of the lights as i have two different lights and i am trying to find out which is correct

The rubber based rear lights were used on Fruehauf Trailers
and theye were meased across the lens
T5 for 5" T4 for 4" & side lights may have been T2
I have many of these old lights mostly perished from age
