Lemme try and depending on the model of your switch ...

no light - no remote connection or port in shutdown (except for 6500)

solid orange - port in error disable, spanning-tree negotiation, Trunk to access port mismatch or switch may have a faulty port. Port is shutdown for a 6500.

flashing orange - Depending on your switch, 2900/3500 means duplex mismatch error.

flashing green - port working fine.

Hope this helps. Please rate when applicable.

I'll have a shot at this :)

no light - no link, port shut

solid orange - Not sure I've ever seen a solid orange

flashing orange - can be stp negotiation (listening/learning stages before going to forwarding), error on port (mismatched duplex)

solid green - Link no activity

flashing green - activity on the link

Also for the 3550 and I think the other ones.

solid orange -- no vlan present -- ie; vlan 100 assigned to a port but not present on the vlan database

Hi
I know the question has been answered but I think it is always a good idea to reference the official documentation.
See Table 8 for Led status on the 2960-series switch:
