Nothing. In fac rumour has it that the white aspects are going to
be replaced with blue aspects, to match the blue aspects to be

Buuut...If you do that, then they could be confused with lamps
associated with tripcock testers. Fun eh?

Other than white is also a valid TCT colour too , depending on the

Ahem, as sir will note above, a Tripcock Tester?

But surely that should be TT?
