Adding LEDs to my EZIO8SA relays?

I just got an EZIO8SA to replace some IOLincs I use to control HVAC stuff. So far, it looks like this will be a good move but with a drawback being that I don't have a visual indicator that a relay is on at the EZIO (which is not anywhere near my ISY admin console). There also isn't a button to physically turn them on/off manually but that's less of an issue.

 

Does anyone know if I would be able to connect a small LED between NO and C (the terminals I use) of each relay to give me a visual of the state the relay is in? I'm using some of the relays to run 24VAC to duct dampers and some to "jumper" a setting in my furnace (fan on, fan high speed), also 24VAC. Of course I would look for LEDs that can handle 24V and think they would flicker because of the AC but that wouldn't bother me. Just as long as it would a) work and B) not fry something.

 

Any info or suggestions would be appreciated.
