[RPG] Does casting while greater invisible make the spell effects also invisible

dnd-3.5einvisibilityspells

I'm pretty sure that even if you're greater invisible and cast say, a lightning bolt, while you stay invisible per the spell, that the spells effects are still visible. I can't find a rule citation though, which is what I'm looking for.

Items dropped or put down by an invisible creature become visible; items picked up disappear if tucked into the clothing or pouches worn by the creature. Light, however, never becomes invisible, although a source of light can become so (thus, the effect is that of a light with no visible source). Any part of an item that the subject carries but that extends more than 10 feet from it becomes visible.

(Emphasis mine)

My interpretation of the points I've put in bold is this:

  • Spells that emit light are visible because there is no way to hide it. Lightning, then, would look like it is originating from nowhere; a random spot in the air.

  • Spells that are immediately "fired" from the caster become visible as they are no longer in contact with him and become "dropped." A flying ball of acid would originate, again, from nowhere.

  • Spells that extend from the caster, but don't emit light, do not become visible until they are at least 10 feet away from the caster. (Though for the life of me I can't think of an example for this one.)

  • Items conjured/summoned by the caster are visible until hidden within the casters clothing.

Also of note:

Of course, the subject is not magically silenced, and certain other conditions can render the recipient detectable (such as stepping in a puddle).

So targets can still hear the caster if the spell has a verbal component, and if there are environmental hazards, like rain, certain spells (not to mention the caster) would become easier, if not certain, to detect.
