    Hi there
    Is it ok to use led lights on the 5104RVF relay?
    I have 4 x 5104RVF relays switching all my lighting circuits in the house.
    The led lights in our master bedroom are flickering when light switch is turned off.
    I will check the relay to see if there is any voltage leak
    I have another room where the light won't switch off, I guess that relay will be faulty (closed)

    Yes

    A few mA leaking will cause many leds to flicker, however it would be unusual for a relay to fail in this way. You may have some contamination across the external connections.

    Relays can certainly fail closed if the contacts weld together due to excessive load.

    The only way to confirm all this is to disconnect the loads and test the relay contacts.

    Flashing lights in the off state of a relay output indicates some strange problem.
    Get an electrician to check the voltage at the relay outputs right away.

    Just mentioning the following for consideration.
    I once came across some Philips LED oyster fittings which illuminated with a disconnected active.
    The site had an earthing problem (missing MEN) and on this particular LED fitting a potential between neutral and earth caused it to glow and flash.
    A dangerous situation requiring immediate attention.

    This is a good point. Because many leds only need a few mA to flicker they can show up existing wiring faults that could be dangerous. Get it checked out.

    Thank you all for your comments
    I will get it checked out however I am finding it hard to find a sparky that specializes in cbus lighting circuits
    I live on the Sunshine Coast. Qld
