In this situation above, I classed my lights as Scene lamps.
Yes a few times I was challenged on this, but if the issuer of the WOF is to decline a WOF for your lights; they must show you where it is stated they are not legal in the rule book.
If they don't then they cannot refuse you a WOF by law.
There are no "grey" areas here folks, either the WOF person knows the rules or they have to look them up.
I had quite a heated argument with one chap and have filed a complaint with the LTSA which I am still awaiting a reply, but he passed the lights without question when I went back after other failed work had been fixed?
