I know there are several threads on this issue ,and I have read most of them and tried a number of fixes e.g ballast resistors,dash light etc.
I get the problem of all indicators on whatever way the column switch is positioned.
I have tested the hazard light switch and there is a permanent connection between the wires to the LH (6) and RH (5) indicators - is this correct?
With the hazard switch disconnected and a jumper wire between the Light switch supply (1) and Supply to flasher (3) indicators work correctly. This I assume proves it is not a dodgy earth.
Before I go down the route of installing relays has anyone had this issue?

Sounds like your hazard switch is faulty, they are pretty cheap to buy. I replaced mine as was getting weird indicator issues and everything works properly now.

On the rocker hazard switch, there should not be a connection between the left and right outputs in the off position.
That's one of the things the switch does - it connects both sides to the relay output. Just to be sure, take the dash telltale bulb out when testing.

Thanks to turrican & zeapod.
It was the brand new hazard switch we had fitted.
I took it apart and reassembled it and now all LED lights are working correctly.
