Can you localise the sound, is it the switch or around the relay box?

It sounds like around the speedo area

I would try unscrewing the binnacle and have a listen from behind, you might be able to locate where it's coming from. Moving stuff around in the rats nest of wires in there may well cure it for a while

Have a sniff around - literally - any smell of burning and get it sorted ASAP before it causes a fire.

No burning smell... sometimes when I select full beem the blue light doesn't show on the binnacle, if I turn the lights on and off a few times it works then the lights are fine?

Reads as if you have a bit of a short circuit there somewhere, better to find it before it gets worse. Do you have a battery cut off by the way? if not keep a 10 mm spanner to hand just in case.
