Hazard lights coming on

Hey guys,

Every now and then my hazard lights will come on, they won't flash like normal hazard lights they will just come on and stay on (unless it's just both my indicators at the same time?)
Sometimes they stay on for half a second, sometimes up to 10 seconds.
They can come on 4 times a minute and sometimes it goes a day without happening.

Anyone had this happen or have any thoughts on what might be happening so I can fix it?

Cheers

Dodgy hazards switch will do this

Should also check for dodgy relay.
