Outer Limits 4x4 Board

I bought a driving light switch with an LED indicator light in it and the bloody LED doesn't work.
Done net search and search here and found SFA.
I'm wiring it up through a relay with pickup off the high beam circuit as per standard.
I can switch the spotties on and off ok when high beam is on but the LED doesn't light up.
Its a 4 pin switch, namely Power - Accessory - Ground - Relay (optional)
Have I bought a dud switch or have I wired it up wrong?
Its a Narva 63026 Rocker Switch.
Any help would be good, thanks

That's weird, Wired up Right obvisously, Did you use acc or relay to activate the relay.
