What I wanted to avoid is the long "high intensity flashing white
light" part where alle attributes are combined into one line. The
conditional part would work, and I am fine with that (although I have
only seen it for opening hours and for access so far). It would look
like this:

   airmark=obstacle_light

   + airmark:light:colour:conditional=white at sunrise-sunset;red at sunset-sunrise

   + airmark:light:character=flashing

   + airmark:light:intensity:conditional=high at sunrise-sunset;low at sunset-sunrise

In most cases tagging will be a lot simpler, for example for an
ordinary steady red light:

    airmark=obstacle_light

    + airmark:light:colour=red

    + airmark:light:character=fixed

> The syntax for the light ... has that not already been done for seamark?

Yes, and I am modeling the proposal on that. Several (sub)keys are
used to fully describe all attributes of the light.

I am fine with that. We still need to have airmark=obstacle_light in
the first line in the examples above because there are many other
different aeronautical lights, and we need to denote that the light is
marking an obstacle. The other attributes could use the airmark:light
key, as in the examples above.

I will copy your input to the discussion page for the proposal to keep
all comments in one place.
