Strange noise from under instrument panel

[mox]

When indicating there is a strange noise(sound like crackling) coming from either the instrument panel or underneath it. All indicators are working as should. I recently replaced the mainbeam fuse under the seat.

Any idea what the noise could be? turn signal relay?
