On the other hand, where a tram is running along a road, is there any
need for it to have separate signals? Would it not suffice for it to
have to obey the same red/amber/green traffic lights as other traffic?

Croydon Tramlink doesn't have a signalling system. It's fairer to say
that the traffic light system includes lights targeted at tram
drivers.

Surely the white lights which show horizontal (stop), vertical (go) and
diagonal (junction) count as signals? The drivers certainly treat them like
signals!

Indeed they are. Tram drivers are not required to observe road
(red/amber/green) traffic lights, but there will be a white dot signal head
at the same location. These are also to be found at junctions, level
crossings, and at the section of interlaced track. Elsewhere the trams are
driven on sight.

I didn't say it didn't have signals, I said it didn't have a
signalling system. I'm assuming the lights at junctions are
freestanding installations of minimal complexity, and the tram lights
at road junctions are just traffic lights with unusual heads. There's
nothing more elaborate than that, as far as I know.

That's still a signalling system. A 'system' isn't *always* about technology
