No headlights or full beam but sidelights and all other lights work

[Kermiee]

I have a Ford Fiesta 56 reg 1.4 and I changed my interior light cos it was blue and the fuse blew didn't think nothing of it once I put the new bulb in after finding out the horn shares the fuse with the interior light the next day I have no headlight or full beam but my side lights and fogs work checked fuses and relays new bulbs in new switch on still no joy but there must be voltage going there cos they work on the home safe setting strange any ideas

sounds like a wiring issue, perhaps a short circuit?
