Get the headgasket tested. Any garage will be able to check the coolant system for exhaust gases.

They collect any gases coming out of the expansion tank, they like put something on top of it so the system is still sealed. If there are any exhaust gases present, then the headgasket is leaking. Are the coolant hoses rock hard? is there any weeping coming out the expansion tank vent?

The light also comes on when you're low on water, even if it's not actually overheating yet, but of course you've already checked that...!
